Abstract

Until recently all laser glasses were characterized by a high density of microscopic metallic platinum inclusions which became macroscopic fracture sites when the glass was used in high fluence applications. These inclusions are directly related to the utilization of metallic platinum in the construction of optical glass melters, a practice of critical importance if the resultant glass castings are to be produced with the high homogeneity required for laser applications. Substantial improvements have been made in reducing the number and size distribution of metallic platinum particles in many phosphate laser glasses. This reduction in platinum particle density has been achieved without compromising the physical, optical, or laser properties of these glasses.
