The kinetic dependence of the photorefractive effect in the congruent lithium niobate crystal is determined in the work. The adequacy of the model for calculating the photoelectric fields from the indicatrix of photoinduced light scattering is shown. Two methods for determining the induced birefringence by interferograms and on the parameters of photoinduced light scattering are compared.

Lithium Niobate Crystals

Nominally pure and doped with zinc in a wide concentration range lithium niobate crystals were studied using photoinduced light scattering. Using the parameters of photo-induced scattered light, we determined the values of the photovoltaic and diffusion field intensities in lithium niobate crystals of different compositions. It was found that the values of thephotoelectric field strengths depend on the state of the defect structure of the crystals.

The analysis of structural particularities and optical properties of LiNbO3 : B (0,55, 0,69 and 0,83 mol. % B2O3) was performed by methods of Raman and photoinduced light scattering, infrared absorption and laser conoscopy. It has been established that the boron impurity brings to 1 the distribution coefficient of lithium and niobium in the growing process. Thus, LiNbO3: B crystals grown from a congruent melt approach the stoichiometric crystals in ordering the structural units of the cation sublattice and the Li / Nb ratio.
