The L3 HAPLS pump engine with design pulse energy of 200 J employs two Nd-doped glass amplifiers operating at 10 Hz and cooled by helium gas. Each amplifier is pumped by high power laser diode arrays, each providing an 800-kW peak power. These are the highest peak-power pulsed laser diode arrays in the world.
The femtosecond pulses are generated in a titanium-doped sapphire amplifier.
The L3 HAPLS system will also include real-time controls and a timing system, which will make it possible to synchronize its operation to the facility’s electronic master clock and later to a femtosecond-precision laser clock.
Current parameters of the laser (March 2020): 0.4 PW, energy 11.5 J, lenght of pulse 28 fs repetition rate 3.3 Hz.
