High power cryogenic Yb:YAG disk laser with nanosecond output pulse duration

Abstract

OPCPA amplification of pulses that are several femtosecond order of magnitude requires pumping with picosecond pulses. For a simulation of such pump a laser system for a stretched picosecond pulse amplification has been created in the Institute of Applied Physics RAS: seed laser has been upgraded, a new high average power active cooling cryogenic disk laser head has been developed. New Main amplifier scheme based on this laser heads has been created.
