Abstract: Research on the fabrication of large-sized mirrors for power optics from such materials as invar, SiC, and the 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 employing materials consisting of multilayered cellular structures and porous materials.

Keywords: materials for mirrors, heat transfer, thermal deformation, mirror stability parameters.
