Optical parametric amplification (OPA) is one of the few techniques that allow for amplification of broadband laser pulses. Therefore, it is well suited for amplification of ultra-short laser pulses. At ELI Beamlines, this technique is used in the main broadband amplifers of the L1 and L2 laser systems.
The timing of laser beamlines and their synchronization with ELI systems play a key role in the operations at the ELI facility. The concept of this laser operation recognizes time-driven control in order to assure the correct operation of the laser beamlines themselves and to provide a facility for the synchronized operation of ELI experiments.
The ELI Beamlines facility will be a high-energy, high repetition rate laser pillar of the ELI (Extreme Light Infrastructure) project. The facility will provide pulses from four laser systems. To meet the requirements for high repetition rates, three of these lasers will employ the emerging technology of diode-pumped solid state lasers (DPSSL) for pumping broadband amplifiers. The fourth, the kilojoule laser, will use advanced flashlamp technology with actively cooled gain medium.
