The scattering of laser radiation in window materials gives rise to several effects which have considerable practical importance. The angular distribution of the radiation scattered within the window can be interpreted to aid in understanding the homogeneity and microstructure of the material. The distribution of scattered radiation which escapes from the window may have important consequences for applications of the material in a laser system. The absorption of scattered radiation within the window will confound the measurement of the linear absorption coefficient when a calorimetric absorption technique is employed. Experiments designed to measure the internal scattering distribution, the external scattering distribution and the influence of absorbed scattering on calorimetric absorption are described. Data for CVD ZnSe are presented.
