Chemical laser window measurements. Final report 7 May 1975--6 May 1976
Optical evaluation including absorption coefficient frequency dependence, surface quality, and absorption coefficient determination at the DF laser frequency has been performed for commerically prepared disk shaped samples of potential DF laser window materials. In addition, some of the samples have been exposed to beam intensities of 1600 w/sq. cm. During these exposure tests, a lateral shearing interferometer was used to observe distortion of the surface. The results of the above measurements are presented. Values obtained for the absorption coefficient frequency dependence and the absorption coefficient at 3.8 micrometers are compared to the best values previously obtained in the UAH laboratory for like materials.
