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.
