High-power solid state lasers with improved beam quality

摘要

Abstract: In this talk the affects that determine the beam quality of high power Nd:YAG lasers are discussed. Suggestions are made on how the beam quality can be improved. Experimental results concerning the relationship of output power and beam quality are presented. The different sources of thermo-optical aberrations in rod and slab lasers that influence the beam quality of stable resonators are discussed. Design criteria for rod and slab lasers with improved beam quality are presented and the direction of future work is outlined. !12
