Front-end system for Yb : YAG cryogenic disk laser

摘要

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 J at a pulse repetition rate of 49 kHz, a pulse duration of similar to 2 ns and a bandwidth of similar to 1.5 nm. After increasing the pump power of the regenerative amplifier, it is expected to achieve a pulse energy of similar to 1 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.
