Abstract

Raman scattering in nominally pure lithium niobate (LiNbO₃) and lithium tantalate (LiTaO₃) crystals has been studied at high-intensity excitation. Significant photoinduced perturbations of Raman spectra of congruently melting LiNbO₃ are discovered in contrast to Raman scattering observed in both nearly stoichiometric LiNbO₃ and congruently melting LiTaO₃. Our study allows assignment of these perturbations to the photorefractive (PR) effect and, therefore, comparison of the PR damage resistance of the crystals studied.
