doi: 10.1117/12.2270598
We report on the status of the high repetition rate, high energy, L1 laser beamline at the ELI-Beamlines facility. The beamline is based on picosecond optical parametric chirped pulse amplification (OPCPA) of pulses from a mode-locked Ti:Sapphire oscillator and has a target energy/repetition rate of 100 mJ/1 kHz with < 15fs pulse duration. The OPCPA pump lasers use thin disk technology to achieve the high energy and average power required to pump such a high energy, high repetition rate broadband amplifier. Here we report on the progress in beamline development and discuss the technical challenges involved in producing such a system and their solutions. A major focus of the laser development is reliable, robust operation and long term stability; mechanical, optical, and control system architecture design considerations to achieve our goals of long term stability are discussed.

Active Cavity Stabilization for High Energy Thin Disk Regenerative Amplifier
High-Power,High-Energy and High-Intensity Laser technology III, edt by Joachim Hein,Proc.of SPIE Vol.10238.CCC code 0277-786X/17/$18
doi: 10.1117/12.2270607
Anglická anotace: We present an active cavity pointing stabilization system based on a novel method that tracks the cavity mode position directly on the thin disk gain medium itself. Here, the overlap of the lasing cavity with the pump, visible as a depletion within the pumped area, is most crucial to the stability of the laser. Short term stability as well as long term stability are significantly increased enabling day long operation, directly from a cold start of the laser system, without the need for thermalization and manual alignment.

High average power, diode pumped Petawatt laser systems: a new generation of lasers enabling precision science and commercial applications
SPIE
doi: 10.1117/12.2281050
Large laser systems that deliver optical pulses with peak powers exceeding one Petawatt (PW) have been constructed at dozens of research facilities worldwide and have fostered research in High-Energy-Density (HED) Science, High-Field and nonlinear physics [1]. Furthermore, the high intensities exceeding 1018W/cm2 allow for efficiently driving secondary sources that inherit some of the properties of the laser pulse. In the intervening decades since that first PW laser, single-shot proof-of-principle experiments have been successful in demonstrating new high-intensity laser-matter interactions and subsequent secondary particle and photon sources. These secondary sources include generation and acceleration of charged-particle (electron, proton, ion) and neutron beams, and x-ray and gamma-ray sources, generation of radioisotopes for positron emission tomography (PET), targeted cancer therapy, medical imaging, and the transmutation of radioactive waste [2, 3].

X-ray phase contrast imaging of biological samples using a betatron x-ray source generated in a laser wakefield accelerator
SPIE Optics + Optoelectronics
doi: 10.1117/12.2265043
In a plasma wakefield accelerator, an intense laser pulse propagates in an under-dense plasma that drives a relativistic plasma wave in which electrons can be injected and accelerated to relativistic energies within a short distance. These accelerated electrons undergo betatron oscillation and emit a collimated X-ray beam along the direction of electron velocity.

Synchronizing single-shot high-energy iodine photodissociation laser PALS and high-repetition-rate femtosecond Ti:sapphire laser system
Rev. Sci. Instrum. 88 (2017) 102711-1 - 102711-11.
doi: 10.1063/1.4979810
A system of precise pulse synchronization between a single-shot large-scale laser exploiting an acousto-optical modulator and a femtosecond high repetition rate laser is reported in this article. This opto-electronical system has been developed for synchronization of the sub-nanosecond kJ-class iodine photodissociation laser system (Prague Asterix Laser System—PALS) with the femtosecond 25-TW Ti:sapphire (Ti:Sa) laser operating at a repetition rate 1 kHz or 10 Hz depending on the required energy level of output pulses. At 1 kHz synchronization regime, a single femtosecond pulse of duration about 45 fs and a small energy less than 1 mJ are exploited as a probe beam for irradiation of a three-frame interferometer, while at 10 Hz repetition rate a single femtosecond pulse with higher energy about 7–10 mJ is exploited as a probe beam for irradiation of a two-channel polaro-interferometer. The synchronization accuracy ±100 ps between the PALS and the Ti:Sa laser pulses has been achieved in both regimes of synchronization. The femtosecond interferograms of laser-produced plasmas obtained by the three-frame interferometer and the femtosecond polarimetric images obtained by the two-frame polaro-interferometer confirm the full usefulness and correct functionality of the proposed method of synchronization.

Laser-induced damage threshold tests of ultrafast multilayer dielectric coatings in various environmental conditions relevant for operation of ELI beamlines laser systems
Opt. Eng. 56 (2017) 011024 - 011024.
doi: 10.1117/1.OE.56.1.011024
Increasing the laser-induced damage resistance of optical components is one of the major challenges in the development of Peta-watt (PW) class laser systems. The extreme light infrastructure (ELI) beamlines project will provide ultrafast laser systems with peak powers up to 10 PW available every minute and PW class beams at 10 Hz complemented by a 5-TW, 1-kHz beamline. Sustainable performance of PW class laser systems relies on the durability of the employed optical components. As part of an effort to evaluate the damage resistance of components utilized in ELI beamlines systems, damage thresholds of several optical multilayer dielectric coatings were measured with different laser parameters and in different environments. Three coatings were tested with 10 Hz and 1 kHz pulse repetition rates, and the effect of a cleaning treatment on their damage resistance was examined.

Multi-channel, fiber-based seed pulse distribution system for femtosecond-level synchronized chirped pulse amplifiers
(2017) -.
doi: 10.1063/1.4974272
We report on the design and performance of a fiber-based, multi-channel laser amplifier seed pulse distribution system. The device is designed to condition and distribute low energy laser pulses from a mode-locked oscillator to multiple, highly synchronized, high energy amplifiers integrated into a laser beamline. Critical functions such as temporal pulse stretching well beyond 100 ps/nm, pulse picking, and fine control over the pulse delay up to 300 ps are all performed in fiber.The design of this system allows for complete computer control of all functions, including tuning of dispersion, and is entirely hands-free. The performance of this device and its subsystems will be relevant to those developing lasers where reliability, size, and cost are key concerns in addition to performance; this includes those developing large-scale laser systems similar to ours and also those developing table-top experiments and commercial systems.

Picosecond pulse generated supercontinuum as a stable seed for OPCPA
Opt. Lett. 42 (2017) 843 - 846.
doi: 10.1364/OL.42.000843
We present a stable supercontinuum (SC) generated in a bulk YAG crystal, pumped by 3 ps chirped pulses at 1030 nm. The SC is generated in a loose focus geometry in a 13 cm long YAG crystal, allowing for stable and robust single-filament generation. The SC energy stability exceeds that of the pump laser by almost a factor of 3. Additionally, we show that the SC spectrum has long-term stability and that the SC is coherent and compressible by compressing the portions of SC spectra close to the corresponding Fourier limit. This makes the picosecond-pulse-driven SC a suitable stable seed for OPCPA amplifiers.
Key words: We present a stable supercontinuum (SC) generated in a bulk YAG crystal, pumped by 3 ps chirped pulses at 1030 nm. The SC is generated in a loose focu

Kinetic magnetization by fast electrons in laser-produced plasmas at sub-relativistic intensities
Phys. Plasmas 24 (2017) 102711-1 - 102711-11.
doi: 10.1063/1.4995044
The problem of spontaneous magnetic field generation with nanosecond laser pulses raises a series of fundamental questions, including the intrinsic magnetization mechanisms in laser-driven plasmas and the understanding of charge-discharge processes in the irradiated target. These two issues are tightly bound as the charge-discharge processes are defined by the currents, which have in turn a feedback by magnetic fields in the plasma. Using direct polaro-interferometric measurements and theoretical analysis, we show that at parameters related to the PALS laser system, fast electrons play a decisive role in the generation of magnetic fields in the laser-driven plasma. Spatial distributions of currents were calculated from the measured magnetic field and plasma density distributions. The obtained results revealed the characteristics of strong currents observed in capacitor-coil magnetic generation schemes and open a new approach to fundamental studies related to magnetized plasmas.
Key words: Laser-produced plasma, femtosecond polaro-interferometry, spontaneous magnetic fiel, spatial and temporal electron density distribution

ELI-beamlines: Progress in development of next generation short-pulse laser systems
SPIE Optics + Optoelectronics
doi: 10.1117/12.2269818
Overview of progress in construction and testing of the laser systems of ELI-Beamlines, accomplished since 2015, is presented. Good progress has been achieved in construction of all four lasers based largely on the technology of diode-pumped solid state lasers (DPSSL). The first part of the L1 laser, designed to provide 200 mJ <15 fs pulses at 1 kHz repetition rate, is up and running. The L2 is a development line employing a 10 J / 10 Hz cryogenic gas-cooled pump laser which has recently been equipped with an advanced cryogenic engine. Operation of the L3-HAPLS system, using a gas-cooled DPSSL pump laser and a Ti:sapphire broadband amplifier, was recently demonstrated at 16 J / 28 fs, at 3.33 Hz rep rate. Finally, the 5 Hz OPCPA front end of the L4 kJ laser is up running and amplification in the Nd:glass large-aperture power amplifiers was demonstrated.

Experimental study of the interaction of two laser-driven radiative shocks at the PALS laser
High Energy Density Physics 23 (2017) 20 - 30.
doi: 10.1016/j.hedp.2017.03.001
Radiative shocks (RS) are complex phenomena which are ubiquitous in astrophysical environments. The study of such hypersonic shocks in the laboratory, under controlled conditions, is of primary interest to understand the physics at play and also to check the ability of numerical simulations to reproduce the experimental results. In this context, we conducted, at the Prague Asterix Laser System facility (PALS), the first experiments dedicated to the study of two counter-propagating radiative shocks propagating at non-equal speeds up to 25–50 km/s in noble gases at pressures ranging between 0.1 and 0.6 bar. These experiments highlighted the interaction between the two radiative precursors. This interaction is qualitatively but not quantitatively described by 1D simulations. Preliminary results obtained with XUV spectroscopy leading to the estimation of shock temperature and ion charge of the plasma are also presented.

doi: 10.1117/12.2270477
A comparison of various pulse stretcher designs accommodating material dispersion for a < 150 fs 10 PW Nd:glass laser system using low dispersion diffraction gratings is presented. Since the pulse amplification demands a high stretch ratio of the stretcher to suppress non-linear effects and a high temporal contrast of the pulse is required to avoid ionization of the experimental targets, the design of the stretcher is a critical part for dispersion management. Here, we compare several designs using only one diffraction grating based on either a Perry-Banks or an Offner stretcher types, mostly at the Littrow angle. The target spectral phase profile is achieved through the tuning of the grating position, the angle of incidence on the grating, the radii of curvature of curved mirrors and the line density of the grating.

Tiled-grating compressors of ultra-short pulse multi-petawatt lasers are currently the only viable way how to meet beam size requirements and stay within the damage threshold of the largest available gratings. Recently, a method how to double the effective aperture of compressor gratings by phasing them with perpendicularly positioned mirrors has been proposed, providing simplification to the traditional grating-grating tiling scheme by reducing the number of alignment degrees of freedom. The drawback of the method lies in tighter requirements on adjustment precision and stability of the system making the alignment and monitoring a challenging task. Here we propose and analyze different approaches to precision control of mirror-grating phasing and present a comparative experimental verification of the alignment systems on a small-scale test bench.

Tiled-grating compressors of ultra-short pulse multi-petawatt lasers are currently the only viable way how to meet beam size requirements and stay within the damage threshold of the largest available gratings. Recently, a method how to double the effective aperture of compressor gratings by phasing them with perpendicularly positioned mirrors has been proposed, providing simplification to the traditional grating-grating tiling scheme by reducing the number of alignment degrees of freedom. The drawback of the method lies in tighter requirements on adjustment precision and stability of the system making the alignment and monitoring a challenging task. Here we propose and analyze different approaches to precision control of mirror-grating phasing and present a comparative experimental verification of the alignment systems on a small-scale test bench.

doi: 10.1016/j.mre.2017.03.003
ELI-Beamlines (ELI-BL), one of the three pillars of the Extreme Light Infrastructure endeavour, will be in a unique position to perform research in high-energy-density-physics (HEDP), plasma physics and ultra-high intensity (UHI) ð >1022W=cm2Þ lasere plasma interaction. Recently the need for HED laboratory physics was identified and the P3 (plasma physics platform) installation under construction in ELI-BL will be an answer. The ELI-BL 10 PW laser makes possible fundamental research topics from high-field physics to new extreme states of matter suchas radiation-dominated ones, high-pressure quantum ones, warm dense matter (WDM) and ultra-relativistic plasmas.

We generate narrowband terahertz (THz) radiation in periodically poled lithium niobate (PPLN) crystals using two chirped-and-delayed driver pulses from a high-energy Ti: sapphire laser. The generated frequency is determined by the phase-matching condition in the PPLN and influences the temporal delay of the two pulses for efficient terahertz generation.

Among the macromolecular drug targets in neurodegenerative disorders, the neurotrophin brain-derived neurotrophic factor (BDNF) and its high-affinity tropomyosin-related kinase receptor (TrkB) present strong interest for nanomedicine development aiming at neuronal and synaptic repair. Currently, BDNF is regarded as the neurotrophic factor of highest therapeutic significance. However, BDNF has delivery problems as a protein drug. The enhanced activation of the transcription factor CREB (cAMP response element- binding protein) has been evidenced to increase the BDNF gene expression and hence the productionof endogenous BDNF.

Recently developed macromolecular drugs display strong potential to cure diseases involving genetic components, e.g. Rheumatoid arthritis, diabetes, Alzheimer's disease, Huntington's disease, Duchenne muscular dystrophy, Retinitis pigmentosa, and several types of cancers. Bioavailability and enhanced drug specificity necessitate the preparation of efficient carrier systems for themacromolecular therapeutics. We employ synchrotron smallangle X-ray scattering (SAXS) and cryogenic transmission electron microscopy (Cryo-TEM) to study the nanostructure formation,macromolecular drug upload, and the topological transformations occurring upon complexation of supercoiled plasmidDNA (encoding for the therapeutic protein brain-derived neurotrophic factor, BDNF) with cationic lipid nanocarrier assemblies.

Laser-driven electron beam generation for secondary photon sources with few terawatt laser pulses

doi: 10.1117/12.2265875
Relativistic electron beams accelerated by laser wakefield have the ability to serve as sources of collimated, point-like and femtosecond X-ray radiation. Experimental conditions for generation of stable quasi-monoenergetic electron bunches using a femtosecond few-terawatt laser pulse (600 mJ, 50 fs) were investigated as they are crucial for generation of stable betatron radiation and X-ray pulses from inverse Compton scattering. A mixture of helium with argon, and helium with an admixture of synthetic air were tested for this purpose using different backing pressures and the obtained results are compared.

Double‑electron ionization driven by inhomogeneous fields

doi: 10.1007/s00340-017-6672-4
Electron-electron correlation effects play a crucial role in our understanding of sequential (SDI) and non-sequential double ionization (NSDI) mechanisms. Here, we present a theoretical study of NSDI driven by plasmonic-enhanced spatial inhomogeneous fields. By numerically solving the time-dependent Schrdinger equation for a linear reduced model of He and a double-electron time-evolution probability analysis, we provide evidence for enhancement effects in NSDI showing that the double ionization yield at lower laser peak intensities is increased due to the spatial inhomogeneous character of plasmonicenhanced field. The change in the emission direction of the double-ion as a function of the field inhomogeneity degree demonstrates that plasmonic-enhanced fields could configure a reliable instrument to control the ion emission.

In a plasma wakefield accelerator, an intense laser pulse propagates in an under-dense plasma that drives a relativistic plasma wave in which electrons can be injected and accelerated to relativistic energies within a short distance. These accelerated electrons undergo betatron oscillation and emit a collimated X-ray beam along the direction of electron velocity.

The optical properties of several commonly used single-crystal oxide substrates were explored by spectroscopic ellipsometry over a wide spectral range from 0.74 eV to 8.8 eV. The crystals examined are (100) SrTiO3, 0.7 % wt Nb-doped (100) SrTiO3,(100) (LaAlO3)0,29(SrAl0,5Ta0,5O3)0,7, (011) DyScO3, (100) MgAl2O4, (100) MgO, and (100) LaAlO3, all of which enable epitaxial growth of numerous perovskite-type and other optical thin films. An analytic form for the complex dielectric function was derived from ellipsometric data through a physically consistent modeling process. The obtained dielectric spectra were further utilized to calculate the complex index of refraction and absorption coefficient for each substrate material. The absorption spectra and optical band gap were analyzed using Tauc plots. The parameters for reconstructing the dielectric functions are given in detail, allowing for extensive applications of the results of this work.

Recently two emerging areas of research, attosecond and nanoscale physics, have started to come together. Attosecond physics deals with phenomena occurring when ultrashort laser pulses, with duration on the femto- and sub-femtosecond time scales, interact with atoms, molecules or solids. The laser-induced electron dynamics occurs natively on a timescale down to a few hundred or even tens of attoseconds (1 attosecond = 1 as = 10−18 s), which is comparable with the optical field. For comparison, the revolution of an electron on a 1s orbital of a hydrogen atom is ∼152 as.

Hot electrons represent a key subject for high intensity laser produced plasmas and atomic physics. Simulations of the radiative properties indicate a high sensitivity to hot electrons, that in turn provides the possibility for their detailed characterization by high-resolution spectroscopic methods. Of particular interest is X-ray spectroscopy due to reduced photo-absorption in dense matter and their efficient generation by hot electrons (inner-shionization/excitation). Here, we report on an experimental campaign conducted at the ns, kJ laser facility PALS at Prague in Czech Republic.

Laser-plasma interactions in the novel regime of relativistically induced transparency (RIT) have been harnessed to generate intense ion beams efficiently with average energies exceeding 10MeV/nucleon (>100MeV for protons) at “table-top” scales in experiments at the LANL Trident Laser. By further optimization of the laser and target, the RIT regime has been extended into a self-organized plasma mode. This mode yields an ion beam with much narrower energy spread while maintaining high ion energy and conversion efficiency. This mode involves self-generation of persistent high magnetic fields (104 T, according to particle-in-cell simulations of the experiments) at the rear-side of the plasma. These magnetic fields trap the laser-heated multi-MeV electrons, which generate a high localized electrostatic field (0.1 TV/m).

Table-top laser systems, using the chirped-pulse amplification (CPA) technique, which were developed in the last decades, are able to reach ultrahigh intensities (above 1018 W=cm2) through the generation of femtosecond laser pulses [1], thus offering new possibilities in the study of relativistic laser-matter interactions [2,3].Among others, laser-driven ion acceleration is one of the most promising and intensively investigated research topics [4], where target normal sheath acceleration (TNSA) is the experimentally most investigated technique.

Nano-spheres deposited on the front (laser irradiated) surface of a flat Mylar foil enabled a small enhancement of the maximum energy and number of the accelerated protons. Nano-spheres on the rear side allowed to modify the proton beam spatial profile. In particular, with nanospheres deposited on the rear of the target, the proton beam spatial homogeneity was clearly enhanced. Silicon nitride thin foils having micro grating structures (with different step dimensions) on the rear surface were also used as targets to influence the divergence of the proton beam and drastically change its shape through a sort of stretching effect.

The nonlocal theory of the radiative energy transport in laser-heated plasmas of arbitrary ratio of the characteristic inhomogeneity scale length to the photon mean free paths is applied to define the closure relations of a hydrodynamic system. The corresponding transport phenomena cannot be described accurately using the Chapman-Enskog approach, that is, with the usual fluid approach dealing only with local values and derivatives. Thus, we directly solve the photon transport equation allowing one to take into account the effect of long-range photon transport. The proposed approach is based on the Bhatnagar-Gross-Krook collision operator using the photon mean free path as a unique parameter.

With the advent of 10 PW laser facilities, new regimes of laser-matter interaction are opening since e
ects of quantum electrodynamics, such as electron-positron pair production and cascade development, start to be important. The dynamics of light charged particles, such as electrons and positrons, is a
ected by the radiation reaction force. This e
ect can strongly in uence the interaction of intense laser pulses with matter since it lowers the energy of emitting particles and transforms their energy to the gamma radiation. Consequently, electron- positron pairs can be generated via Breit-Wheeler process. To study this new regime of interaction, numerical simulations are required.

The intensities of the order of 10(23-24) W/cm(2) are required to efficiently generate electron-positron pairs in laser-matter interaction when multiple laser beam collision is employed. To achieve such intense laser fields with the upcoming generation of 10 PW laser beams, focusing to sub-micron spot size is required. In this paper, the possibility of pair production cascade development is studied for the case of a standing wave created by two tightly focused colliding laser pulses.

Phases of plasma produced with nanosecond laser
44th EPS Conference on Plasma Physics. In europhysics conference abstracts, Vol. 41F, ISBN: 979-10-96389-07, P2.205.
Our experimental studies have shown that the time-resolved target current indicates the occurrence of various phases of the laser-produced plasma. During the first plasma phase defined by the duration of laser-target interaction, the time derivative of the target current matches the time-resolved laser intensity. The second phase of the laser-produced plasma starts after termination of the laser-matter interaction. For the entire duration of this active phase, the plasma surviving on the target surface emits transient electromagnetic radiation (EMP), X-ray radiation, and slow ions. This surface plasma causes the target charging balanced by a return target current on a time scale of 100 ns. Then the target holder acts as a probe, the signal of which can indicate a residual plasma persisting inside the target chamber on a time scale of microseconds.

The current balancing the target charging and the emission of transient electromagnetic pulses (EMP) driven by the interaction of a focused 1.315 μm iodine 300 ps PALS laser with metallic and plastic targets were measured with the use of inductive probes. It is experimentally proven that the duration of return target currents and EMPs is much longer than the duration of laser-target interaction. The laser-produced plasma is active after the laser-target interaction. During this phase, the target acts as a virtual cathode and the plasma-target interface expands. A double exponential function is used in order to obtain the temporal characteristics of EMP. The rise time of EMPs fluctuates in the range up to a few tens of nanoseconds. Frequency spectra of EMP and target currents are modified by resonant frequencies of the interaction chamber.

The essence of the FBP is that the Schrödinger equation is not analytically solvable for more than two mutually interacting particles even when the underlying forces are precisely known

Electron vortices appear in the wake of a
nite length laser pulse propogating in the underdense plasma. Usually they form two chains of vortices with opposite signs of the magnetic
elds locked inside an electron cavity. Using 2D PIC simulations, we discuss the e
ects of evolution of single and binary electron vortices. Single electron vortices, though being in a quasistationary state on electron timescales, evolve on ion timescales, leading to anisotropic multishell ion motion.

Monolayers of polystyrene nanospheres were placed on the rear surfaces of thin plastic targets to improve the spatial homogeneity of the accelerated proton beams. Moreover, thin targets with grating structures of various configurations on their rear sides were used to modify the proton beam divergence.

Electromagnetic pulse (EMP) radiation by laser interaction with a solid H2 ribbon
Phys. Plasmas 24 (2017) 083103(1) - 083103(6).
doi: 10.1063/1.4995475
The electromagnetic pulses (EMPs) generated during the interaction of a focused 1.315-μm sub-nanosecond laser pulse with a solid hydrogen ribbon were measured. The strength and temporal characteristics of EMPs were found to be dependent on the target density. If a low density target is ionized during the interaction with the laser, and the plasma does not physically touch the target holder, the EMP is weaker in strength and shorter in time duration. It is shown that during the H2 target experiment, the EMP does not strongly affect the response of fast electronic devices. The measurements of the EMP were carried out by Rohde&Schwarz B-Probes, particularly sensitive in the frequency range from 30 MHz and 1 GHz. Numerical simulations of resonant frequencies of the target chamber used in the experiment at the Prague Asterix Laser System kJ-class laser facility elucidate the peaked structure of EMP frequency spectra in the GHz domain.

We study the role of the projectile coherence in collision processes. We analyze in particular the ionization of He by p+ and C6+ projectiles at 1 and 100 MeV/amu, respectively. We compare the influence of this effect in both cases by performing a First Born calculation convoluted with a gaussian distribution, which accounts for the initial incoherence of the projectile wave packet. Even though this is the simplest approach that one could implement to solve this problem, it gives good agreement with the experimental results.

Emergence of a Higher Energy Structure in Strong Field Ionization with Inhomogeneous Electric Fields
Phys. Rev. Lett. 119 (2017) 053204 (1) - 053204 (5).
doi: 10.1103/PhysRevLett.119.053204
Studies of strong field ionization have historically relied on the strong field approximation, which neglects all spatial dependence in the forces experienced by the electron after ionization. More recently, the small spatial inhomogeneity introduced by the long-range Coulomb potential has been linked to a number of important features in the photoelectron spectrum, such as Coulomb asymmetry, Coulomb focusing, and the low energy structure. Here, we demonstrate using midinfrared laser wavelength that a time-varying spatial dependence in the laser electric field, such as that produced in the vicinity of a nanostructure, creates a prominent higher energy peak.

Emission of high-order harmonics from solids provides a new avenue in attosecond science. On the one hand, it allows us to investigate fundamental processes of the nonlinear response of electrons driven by a strong laser pulse in a periodic crystal lattice. On the other hand, it opens new paths toward efficient attosecond pulse generation, novel imaging of electronic wave functions, and enhancement of high-order harmonic-generation (HHG) intensity.

Study of gamma-ray emission by proton beam interaction with injected Boron atoms for future medical imaging applications
JINST 12 (2017) C03049(1)
doi: 10.1088/1748-0221/12/03/C03049

In this work an experimental and theoretical study of gamma-prompt emission has been carried out with the main aim being to understand to what extent this approach can be used during a treatment based on proton-boron fusion therapy. An experimental campaign, carried out with a high purity Germanium detector, has been performed to evaluate the gamma emission from two pure B-11 and B-10 targets. Furthermore, a set of analytical simulations, using the Talys nuclear reaction code has been performed and the calculated spectra compared with the experimental results. These comparisons allowed us to successfully validate Talys which was then used to estimate the gamma emission when a realistic Boron concentration was considered.

Prompt gamma-ray emission for future imaging applications in proton-boron fusion therapy

Recently, an approach exploiting the proton therapy biological enhancement by using Boron atoms injected inside a tumor, has been proposed [1–3]. Here, the 11B(p,)2 nuclear fusion reaction channel, where three alpha particles are produced with an average energy around 4MeV, is considered [4]. These alphas are able to penetrate the cells nucleus and strongly damage their DNA. In addition, gamma prompts emitted by the proton Boron nuclear reactions can be used for on-line proton beam imaging purposes.

doi: 10.1088/1748-0221/12/03/C03027
In this paper, we present a Geant4-based Monte Carlo application for ELIMED beamline [1–6] simulation, including its features and several preliminary results. We have developed the application to aid the design of the beamline, to estimate various beam characteristics, and to assess the amount of secondary radiation. In future, an enhanced version of this application will support the beamline users when preparing their experiments.

Experimental study of the interaction of two laser-driven radiative shocks at the PALS laser
High Energy Density Physics 23 (2017) 20 - 30.
doi: 10.1016/j.hedp.2017.03.001
Radiative shocks (RS) are complex phenomena which are ubiquitous in astrophysical environments. The study of such hypersonic shocks in the laboratory, under controlled conditions, is of primary interest to understand the physics at play and also to check the ability of numerical simulations to reproduce the experimental results. In this context, we conducted, at the Prague Asterix Laser System facility (PALS), the first experiments dedicated to the study of two counter-propagating radiative shocks propagating at non-equal speeds up to 25–50 km/s in noble gases at pressures ranging between 0.1 and 0.6 bar. These experiments highlighted the interaction between the two radiative precursors. This interaction is qualitatively but not quantitatively described by 1D simulations. Preliminary results obtained with XUV spectroscopy leading to the estimation of shock temperature and ion charge of the plasma are also presented.

doi: 10.1063/1.4986464
Highly collimated betatron radiation from a laser wakefield accelerator is a promising tool for spectroscopic measurements. Therefore, there is a requirement to create spectrometers suited to the unique properties of such a source. We demonstrate a spectrometer which achieves an energy resolution of <5 eV at 9 keV (E=E > 1800) and is angularly resolving the x-ray emission allowing the reference and spectrum to be recorded at the same time. The single photon analysis is used to significantly reduce the background noise.

Recent experimental techniques in multicolor waveform synthesis allow the temporal shaping of strong femtosecond laser pulses with applications in the control of quantum mechanical processes in atoms, molecules, and nanostructures. Prediction of the shapes of the optimal waveforms can be done computationally using quantum optimal control theory. In this work we demonstrate the control of above-threshold photoemission of one-dimensional hydrogen model with pulses feasible for experimental waveform synthesis.

Abstract: This work presents optical simulations that are used to design a betatron driven by a short-pulse laser based on the Laser Wakefield Acceleration (LWFA) concept. These simulations explore how the optical setup and its components influence the performance of the betatron. The impact of phase irregularities induced by optical elements is investigated. In order to obtain a good estimate of the future performance of this design a combination of two distinct techniques are used - Field Tracing for optical simulations employing a combination of the Zemax and Virtual Lab computational platforms for the laser beam propagation and focusing with the given optical system and particle-in-cell simulation (PIC) for simulating the short-pulse laser interaction with a gas target.

High-order-harmonic generation (HHG) results from the interaction of ultrashort laser pulses with matter. It configures an invaluable tool to produce attosecond pulses, moreover, to extract electron structural and dynamical information of the target, i.e., atoms, molecules, and solids. In this contribution, we introduce an analytical description of atomic and molecular HHG, that extends the well-established theoretical strong-field approximation (SFA).

doi: 10.1038/s41598-017-01783-4
Raman amplification arising from the excitation of a density echelon in plasma could lead to amplifiers that significantly exceed current power limits of conventional laser media. Here we show that 1–100 J pump pulses can amplify picojoule seed pulses to nearly joule level. The extremely high gain also leads to significant amplification of backscattered radiation from “noise”, arising from stochastic plasma fluctuations that competes with externally injected seed pulses, which are amplified to similar levels at the highest pump energies.

We show experimentally and through numerical simulations that a high-energy electron beam is produced simultaneously with two stable lower energy beams that are ejected in oblique and counter-propagating directions, typically carrying off 5–10% of the initial laser energy.

Sponge-type nanocarriers (spongosomes) are produced upon dispersion of a liquid crystalline spongephase formed by self-assembly of an amphiphilic lipid in excess aqueous phase. The inner organizationof the spongosomes is built-up by randomly ordered bicontinuous lipid membranes and their surfacesare stabilized by alginate chains providing stealth properties and colloidal stability.
