Abstract

Main limiting factor for solid state laser average output power is related to thermal effects in active medium. Optimizing heat removal should be a way to avoid this problem. One of the options is to use cryogenical cooling which is quite complicated for most applications. Other solutions for room temperature are mainly based on relatively large area for heat removal and geometries which allow compensating thermally induced distortions [1,2].
