摘要：

The specific features of photorefractive light scattering in nominally pure stoichiometric (Li/Nb = 1) sin- gle crystals grown from a melt with 58.6 mol % Li(2)O (LiNbO(3)st) and in the stoichiometric single crystals grown from a melt of congruent composition in the presence of K(2)O flux (LiNbO(3)stK(2)O) have been investi- gated. At an excitation power of 30 mW, LiNbO(3)stK(2)O single crystals are found to exhibit a stronger photo- refractive effect than LiNbO(3)st single crystals.
