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 % Li2O (LiNbO3st) and in the stoichiometric single crystals grown from a melt of congruent composition in the presence of K2O flux (LiNbO3stK2O) have been investi- gated. At an excitation power of 30 mW, LiNbO3stK2O single crystals are found to exhibit a stronger photo- refractive effect than LiNbO3st single crystals.
