Abstract :
Summary form only given. The thermal deformations in optical resonator elements of powerful lasers lead to decreasing of resonator stability, to change of spatial parameters of output radiation; and also can cause destruction of optical elements. The results of theoretical researches of temperature fields and deformations depending on the physical characteristics of optical materials, their absorbing ability, and also modes of laser operation are presented in this work. The results of experimental measurements by the interference method of quantity of the thermal deformations in resonator mirrors of powerful lasers are shown. The submitted results allow optimizing parameters of laser resonators for powerful lasers, to prove a choice of optical materials, to simulate the most rational ways a cooling of optical elements
