Investigations into the Feasibility of High Power Laser Window Materials

Abstract

A crystal of CVD zinc selenide was placed in the steady 2 kW beam of a 10.6 micrometers laser. The beam was approximately gaussian with 1/e radius of 0.24 cm. Fifty frame per second motion pictures were taken of the time dependent optical distortion as observed with He-Ne light and a Mach-Zehnder interferometer. Thirty-one circular fringes originated in 10 seconds.
