Paper Abstract

The contributions of individual impurities to the total absorption loss in phosphate laser glasses have been analyzed. In a previous study, small melts with intentional impurities were analyzed as a means of determining the absorption coefficients for specific impurities. Since that study, the conditions for melting of large castings of phosphate glass have been modified toward substantially higher oxygen fugacity so that microscopic platinum inclusions can be dissolved to prevent laser-induced damage. In this study, we present absorption coefficient measurements at the laser wavelength (1.05 pm) for most common transition metal impurities as well as platinum in phosphate laser glasses melted under the modern oxidizing conditions.
