Theoretical Studies of High-Power Ultraviolet and Infrared Materials.

Abstract

The main thrust of the program in the current report period has been on analyzing the expected performance of high-power reflectors and windows for use in the wavelength region from 250 to 350nm, in anticipating potential problems for these reflectors and windows, and in seeking solutions. Several exciting new results were obtained. The abstracts and summaries in the Introduction and Summary subsections of the individual sections provide an outline of the central results. The following list is intended to provide an overview and a very brief summary of the results obtained to date. (1) Theoretical results for the failure modes of reflectors and windows are derived and applied to a model system with wavelengths lambda = 250 to 350nm, pulse duration t(p) = 1 microsecs, repetition rate 100 Hz (to 1000 Hz), reflector absorptance .005, extrinsic window material absorptance .0001 (absorption coefficient beta = .0001/cm for a one-centimeter-thick window), and lambda/40 allowed optical phase distortion.
