Abstract

In this work, the processes resulting in optical parameters change of glasses was investigated during the beforethreshold laser irradiation. Residual changes of refractive index resulting in beam contraction and intensity growth of laser radiation in the caustic center were found to be conditioned by the production of mechanical stresses in the sample bulk. Under multiple laser radiation with h(nu)
