ELI-Beamlines is a research facility dedicated to using high intensity lasers to drive experiments for users and part of the larger ELI – ERIC research consortium. In order to provide the widest range of experimental opportunities in a single facility, ELI Beamlines has 4 state-of-the-art high power lasers with output peak powers ranging from TW to 10 PW levels. The lasers are at varying stages of development with some nearing completion and others already running experimental campaigns for users. Several technologies are utilized in these lasers such as high power diode pumped solid state laser (DPSSL) technology, Sapphire amplification, optical parametric chirped pulse amplification (OPCPA), Nd:glass amplification, and fiber lasers/amplifiers. A brief summary of the beamlines is provided below:
L1-Allegra is a 1 kHz, 50 mJ laser based entirely on thin disk DPSSL pumped picosecond OPCPA. This laser is used regularly for user experiments and is currently being upgraded to have an auxiliary pulse train and a higher output energy of 100 mJ.
L2-DUHA is under development and is designed to be a 100 TW, 50 Hz laser for driving a laser wakefield accelerator. This laser based on high energy OPCPA pumped by a cryogenically cooled Yb:YAG multi-slab DPSSL.
L3-HAPLS is a 10 Hz, 1 PW laser which was developed by Lawrence Livermore National Laboratory. This laser is currently being used in user experiments and performance ramping of the laser to improve the output parameters has begun.
L4-Aton is a kJ-class laser with a design peak power value of 10 PW firing onceevery 5 minutes and based on amplification via OPCPA and Nd:glass. Commissioning is ongoing with a primary focus on compression of the high energy pulse to 10 PW peak power.
