It was demonstrated that the oxidation of platinum followed by the subsequent reduction of the oxide particles to the metal is a major source of inclusions in laser glasses melted in systems containing platinum. These glasses can be melted in platinum without inclusions if an inert atmosphere such as nitrogen or argon replaces oxygen in the system. Laser glasses prepared in this manner have given excellent performance in high energy laser devices. In a parallel but different approach to the elimination of platinum inclusions an all-ceramic melting system was designed and constructed. This system, which utilizes special refractories and stirring techniques, is undergoing preliminary tests.
