Abstract : Theoptical absorption of previously available polycrystalline zinc selenide and cadmium telluride was too extensive to permit the use of these materials in high energy laser windows. The approach used in the program was to make polycrystalline windows by hot-pressing under optimum conditions, making use of starting materials of ordinary purity and stoichiometry which were currently available on a commercial basis. Many ZnSe pressings and a few CdTe pressings were made which possessed essentially theoretical transmittance. Absorption coefficients as ZnSe and CdTe respectively.
