【 摘 要 】

A comparative analysis of photorefractive properties was carried out for congruent, stoichiometric and double doped lithium niobate crystals: LiNbO3 : Fe(0,009) : Mg(5,04) and LiNbO3 : Fe(0,02) : Zn(4,34) mol %. These crystals are different in defect types, which are responsible for the effect of photorefraction. Band gap was shown to be minimal for double-doped crystals, photorefractive effect to be the same as for stoichiometric crystals, and photoinduced light scattering was not observed.
