IR Window Studies

Abstract

Advances were made in the theory of multiple phonon absorption mechanisms, the theory of thermal skewing of asymmetric beams, and in the experimental characterization of IR window materials. Preliminary calorimetric measurements of the absorption coefficient in melt grown chromium-free GaAs versus wavelength yield values lower than any previously measured in chromium doped samples. The results of measurements of the mechanical properties of GaAs, and data related to the defect chemistry of CdTe and CdS are also reported. Systems for the production of ultra pure alkali halide and III-V compounds are nearing completion.
