Researches into the fabrication of large-sized mirrors for power optics from such materials as invar, SiC, and a C—Si—SiC composite material are discussed. Methods to calculate thermal deformations in cooled mirrors under irradiation with light have been developed. A technique to reduce the mirror weight is suggested that is based on using materials consisting of multilayered cellular structures and porous materials.
