Low Loss Window Materials for Chemical Lasers

Abstract

The optical absorption has been measured at DF and HF wavelengths in a wide variety of materials which show promise for use as windows on high powered chemical lasers. These measurements, which were made using DF-HF chemical laser calorimetric techniques, are compiled in this report in an effort to bring together in a systematic fashion all the absorption data taken to date. The identification and characterization of surface absorption mechanisms such as those arising from organic solvents used in surface cleaning and from mechanical polishing, is a major thrust of this report. The specific materials studied in detail include ZnSe, SrF2, Ge, Si, NaF, CaF2, Yttralox and other miscellaneous alkali halides including NaCl, KCl, LiF, and KBr.
