Some Aspects of the Optical Evaluation of CO2 Laser Window Materials at Air Force Cambridge Research Labs. (AFCRL)
Abstract
An overview of some of the theoretical and experimental aspects of the AFCRL optical evaluation program for high-power laser window materials is presented. A vector diffraction theory used to treat the thermal lensing problem is described. Absorption coefficient measurements on state-of-the-art window materials are presented, and problems encountered in optical evaluation by calorimetry are discussed. A new interferometric technique for measuring absorption coefficients of low optical loss materials is described.
