Abstract

Results of development of high-sensitive method of absorption coefficient measurement of lasers resonator mirrors that bases on use of interferometric calorimetry are presented in given work. Essence of method consists in the measurement of deformation of mirror surface in the result of its local heating at incidence of powerful laser beam. Investigated mirror is part of high q-factor Fabry-Perot interferometer and, in the same time is intrinsic resonator of powerful laser, for increasing of method sensitivity.
