Growth and Hardening of Alkali Halides for Use in Infrared Laser Windows.

Abstract

A Reactive Atmosphere Process - Bridgman crystal growth system has been placed in operation. The 10.6 micrometer absorption has been measured for several KCl crystals grown in this system. The crystals show an absorption coefficient of 0.0004/cm-0.0006/cm. The effect of ionizing radiation on the 10.6 micrometer absorption of KCl has been determined. The observed absorption increase was found to be due to the F aggregate centers rather than to the Cl interstitials.
