Abstract
The paper presents the results of studies of the effect of γ-irradiation on the photorefractive properties of lithium niobate (LiNbO3), using optical absorption and Raman spectroscopy of Raman scattering. It is shown that with γ-irradiation, the optical density of the lithium niobate crystal increases, i.e. the shift of the optical absorption edge towards long waves, with an increase in the irradiation dose, the refractive index increases, in the interval 1300 ÷ 1600 cm–1 with γ-irradiation at a frequency of 1375 cm–1, peaks appear due to centers of significant changes in Raman scattering frequencies.
