Abstract

Long wavelength, high energy laser systems frequently utilize molybdenum mirror substrates as high flux components. The optically polished surfaces of these substrates normally possess an objectionable texture variously described as "grain boundary relief", "plateau structure", or "dual plane structure". An optical polishing procedure which greatly reduces and, in some cases, eliminates apparent traces of this texture has been identified. Qualitative documentation in the form of phase contrast micrographs are presented. These illustrate the surface textures of a random selection of molybdenum mirrors which are compared with the textures resulting from various Polishing techniques explored at the Developmental Optics Facility (D0F).
