The program is a study of surface-finishing techniques considered to be capable of improving the surface quality of laser optical materials. Chemical and chemical-mechanical polishing, ion-beam polishing, bowl-feed and continuously recycled abrasive superpolishing techniques will be developed for single-crystal and polycrystalline potassium chloride and calcium fluoride, and polycrystalline zinc selenide. A new class of abrasives which are transparent to infrared laser radiation will be studied.
