Abstract: A repetitively pulsed laser system based on cryogenically cooled Yb : YAG disks is developed. The creation of Yb : YAG/YAG composites and the use of an active liquid nitrogen cooling system made it possible to significantly decrease the effect of amplified spontaneous emission. The average output power of the system is 60 W.

Keywords: pulsed laser, disk laser, Yb :YAG, cryogenic cooling.
