Abstract: A new front-end system for a cryogenic Yb:YAG laser is designed. The system consists of a femtosecond source, a stretcher and a regenerative amplifier with an output energy of $25$ $\mu\mathrm J$ at a pulse repetition rate of $49$ kHz, a pulse duration of $\sim2$ ns and a bandwidth of $\sim1.5~$nm. After increasing the pump power of the regenerative amplifier, it is expected to achieve a pulse energy of $\sim1$ mJ at the input to cryogenic amplification stages, which will allow one to obtain laser pulses with a duration of several picoseconds at the output of the cryogenic laser after compression.

Keywords: pulsed laser, disk laser, Yb:YAG, regenerative amplifier, Bragg gratings, diffraction gratings.
