Abstract

The main purpose of our investigations consists in creation the solid state laser with power approximately 500 W and high beam quality. The beam quality, as well known, is described with parameter M², that characterizes the focusing properties of laser radiation. Notice that the high power technological lasers with lamp pumping have the typical value M² from 20 to 100. It could be decreased by means of use the special technical methods of compensation of birefringence and aberrations in the induced thermal lenses of active elements.
