Abstract

The purpose of this paper is to provide guidelines for assessing the performance of actively cooled high-power/high-energy laser beam (HEL) reflectors. The first segment concerns a highly simplified situation involving steady-state irradiance-mapping distortions only; a comprehensive "mirror figure of merit" may thus be defined for characterizing the performance of HEL reflectors, in the absence of pressure-induced ripples. In the second part, a generalized mirror/heat-exchanger model is used for evaluating the potential impact of coolant-induced distortions, for identifying key properties of mirror materials, and for creating a "material index of goodness" applicable to HEL reflectors; the most promising candidates are silicon carbide and tungsten.
