Abstract

It was shown that the threshold lowering of optical strength of optical materials under multifold pulse laser irradiation can be due to the thermodiffusion solution of the locally- heated inhomogeneities during the pulse laser action. Increasing the inclusion radius leads to increased heating and thermostrains in the matrix near inclusions up to the limit. The local heating of the inclusions is due to the recombination of photoexcited matrix nonequilibrium carriers of charge on inhomogeneities which play the role of a recombination drain.
