Abstract
This invention modifies the microstructure of semiconductor nanocrystallite embedded glass by following a prescribed process schedule, so that it can be a solid state laser active medium. The crystalline phase of the glass consists of uniformly dispersed nanometer size single crystals which belong to one of the following semiconductor compounds: ZnS.sub.x Se.sub.1-x, CdS.sub.x Se.sub.1-x, ZnS.sub.x Te.sub.1-x, ZnSe.sub.x Te.sub.1-x, CuCl.sub.x Br.sub.1-x, InP, Al.sub.x Ga.sub.1-x As, GaInAsP, AlGaAsSb, InAsSbP, and AlGaInP, where x=0 to 1. Some of the semiconductor nanocrystallite embedded glass has a tunable range which overlaps that of the visible dye lasers, therefore it can be used as a replacement for the existing liquid dyes as the active media utilized in the tunable dye laser systems.
