ELI Beamlines is designed as the high-energy, high repetition-rate pillar of the Extreme Light Infrastructure (ELI). The top-level goal in implementing the project, as endorsed in the ELI White Book [1], is to establish a high-energy beam facility, responsible for development and use of ultra-short pulses of high-energy particles and radiation stemming from relativistic and ultrarelativistic interactions. ELI Beamlines is intended to address one of the "grand challenges," specifically in the generation of ultra-short pulses of energetic particles (>10 GeV) and radiation (up to few MeV) beams produced from compact laser plasma accelerators, and is expected to support the "Ultra-high field Science, i.e. access of the ultra-relativistic regime" [5].

The laser resources that will be available at the ELI Beamlines facility have been suggested in the Technical Design Review document [3]. The laser resources described there have been designed to address specific scientific challenges as identified by the international consortium within the ELI Preparatory Phase [2,3], namely in the fields of particle acceleration by lasers, generation of high-brightness XUV and X-ray pulses, and high-field physics. The ultrashort pulsed sources of energetic particles and radiation that are generated are designed to serve fundamental research and multidisciplinary applications.

In response to the objectives of the of ELI Beamlines facility, the laser systems must provide the following main features:

  • Laser pulses with high repetition rates delivering multi-10 TW (terawatt) to PW peak power with high user versatility, for projects featuring fundamental and applied research
  • Ultra-high peak power of 10 PW (petawatt) providing focused intensities up to 1024 W/cm2 at increased shot rates, for fundamental science research projects.
