Abstract
The manner in which the strength parameter is used in the design process for high-average-power slab lasers is examined. Fracture toughness, an intrinsic measure of the strength of brittle materials, is adopted as the appropriate parameter for comparison of different materials in a selection process. Conversely, an estimate of actual component strength is used in fixing a safe operating stress for the laser by a weibull scaling of fracture data. Measurement methods for characterizing these two strength parameters are examined for both laser glasses and crystals. Experimental results illustrating these techniques are given.This publication has 26 references indexed in Scilit:
