High Energy Laser Windows

Abstract

The goal of the program is to improve the mechanical properties of, and reduce the absorption in, alkali halides for laser window use. With KCl as a model material, higher yield strengths and fracture toughness have been achieved by forging crystals to obtain fine grained polycrystalline bodies supplemented by alloying or irradiation. Very low absorption has resulted from improved crystal growth processes and finishing operations. The mechanisms of absorption are being studied both theoretically and experimentally as a guide to further reducing absorption. Advances in these areas are presented and discussed in the report.
