Laser Window Studies
Abstract
This report deals largely with the characterization of films (ZnSe, ZnS, As2S3 and ThF4) on high power laser window substrates (BaF2 and ZnSe). Thus far attenuated total internal reflection spectra have been taken of As2S3 on BaF2; and calorimetric measurements for film absorption studies have been developed and applied to As2S3 on BaF2. A literature search has been undertaken to determine liquid coolants for high power windows but no promising candidates were found. A literature search of the mechanical, physical and chemical properties of films was made. Adhesion measurements have begun using pull tests and peeling tests, as well as microhardness measurements using a small diamond indenter in conjunction with the scanning electron beam microscope.
