Abstract

In the work two models describing interaction of UV laser radiation (LR) with ionic crystals are considered. In the first version the wavelength of LR lies in absorption region of F centers, in the second--it is in a short-wave area of H centers absorption wing. Is shown, that the photodissociation in crystals of F₂^- complexes on two holes is the effective mechanism of defects formation in a crystalline structure. The account of these and other electronic excitation relaxation processes in models allows to explain many experimental results of LR action on ionic crystals.
