Abstract : Progress is presented of research underway on the identification, preparation, and evaluation of materials with properties suitable for use as high power laser windows. Results are given on the growth of selected halides, III-V, and II-VI crystals, measurements of physical properties, surface-damage studies, and related measurements into laser beam distortion, optical absorption, and refractive index. Also, a diffraction theory of aberrations is introduced that provides a detailed, three-dimensional intensity distribution in all of space and for all time, as well as the ability to formulate lensing criteria.
