High Energy Laser Windows

Abstract

The report describes work done to develop and alkali halide window with suitable characteristics for laser uses. Alkali halides have a number of attractive properties that recommend them for windows for infrared lasers. A goal of this program is to improve the mechanical properties of the alkali halides by developing polycrystalline materials without destroying their excellent optical properties. The technique of press forging has been used. Progress has been made in developing chemical polishing techniques as a final step after mechanical polishing to insure a smooth surface. A theoretical study of the source of optical absorption has been made for alkali halides at frequencies far higher than the 'Restrahl' frequencies.
