Abstract : The properties of a soda-lime-silicate laser glass known as Code 0580 glass are reported. This includes spectral properties, glass properties, composition, laser threshold, and impurity analysis. The variation of the optical path through a laser rod during flash illumination has been observed. Factors important in understanding this effect are discussed and experimental measurement of them described. Laser damage experiments performed by Westinghouse on 17 different kinds of Corning glass, selected for their unique properties, were analyzed. Four possible mechanisms were advanced. An analysis showed that long lifetimes and high neodymium concentrations are the most important parameters for high energy storage. A new technique was developed to measure thresholds using constant spectral and temporal pump light. (Author)
