ELI Beamlines reached the highest average power ever demonstrated by a petawatt laser
Operation of the L3-HAPLS laser system (ELI Beamlines Research Centre) at 0.5 PW level was demonstrated through compression of the full energy output pulses currently generated by the laser chain, in the Petawatt vacuum compressor. The L3-HAPLS is a system designed for sustained operation with repetition rate 10 Hz.
