The goal of the program is to improve the strength and fracture behavior of alkali halides while retaining their low absorption for laser window use. The approach of plastically deforming single cyrstals press forging to obtain a fine grain polycrystalline body has been previously shown to increase yield stresses by an order of magnitude to about 5000 psi. In the report, further advances in raising strengths and lowering absorption are presented.
