Abstract:

The report delineates efforts expended on a project which required an analysis in depth of thermal distortion of wavefronts in large laser rods and discs. Two approaches for elimination of this distortion were considered 1 establishment of a uniform temperature throughout the laser during pumping and 2 development of athermal glass parameters. Elements of both approaches were found necessary to solve the problem. In separate sections of the report detailed treatments are given to thermally stable cavities, temperature profile calculations, the effect of the laser field on index of refraction of the laser rod, and finally an analysis of end region stress.
