Abstract : A high average power CW Nd:YAG laser has been built and is described. This laser has been operated with both tungsten and krypton pump lamps, with superior performance occurring during krypton pumping. Measurements of the thermal properties (thermal focusing and birefringence) of krypton-pumped Nd:YAG lasers are presented. Also presented are the results of a variety of experiments aimed at compensating for the thermally induced birefringence in Nd:YAG laser rods. To date, using compensation, we have reduced the polarization losses in a Nd:YAG laser rod by a factor of 12. (Author)
