The goal of the investigation is the elimination of platinum particles in laser glass. For glasses melted in platinum crucibles, earlier work indicates that platinum -free glasses may be obtained if the glass is melted in an inert atmosphere. Various methods of homogenizing the glass in an atmosphere furnace, other than stirring, were investigated including bubbling inert gas through the melt, convection currents and diffusion. A parallel approach to this problem, also being investigated, is the melting of high purity laser glass in an all-ceramic system. Such a system was constructed and tested. Problem areas were identified and design modifications were made where necessary. Optimization of the operational procedure of the furnace is now in progress. Author
