Optical Materials Characterization
Abstract
A program has been established for measuring refractive index, stress-optical constants, ij, change of index with temperature, thermal expansion coefficient, and elastic compliances, ij, of infrared laser window materials. These parameters are necessary for determining the optical distortion that occurs in windows due to heating by the absorption of high power laser radiation. Materials currently under study are polycrystalline ZnSe, As2S3 glass, chalcogenide glass (Ge 33%, As 12%, Se 55%), and KCl.
