中文摘要：

对于掺铁铌酸锂晶体中不同全息记录配置下的磁光折变效应做了比较系统的理论分析,给出了铌酸锂晶体所有的磁光生伏打非零张量元.详细计算并给出了不同全息纪录配置下的所有体光生伏打、磁光生伏打电流的解析形式.理论结果表明,由于磁光生伏打效应引起了光激发电流的变化,所以对于每种配置全息光栅的衍射效率都会受到外加磁场的影响;对于不同的全息记录配置,磁场对铌酸锂晶体光折变非线性性质的影响也不同.讨论了一种确定特定张量元的方法.

英文摘要：

A theoretical analysis of the magneto-photorefractive effect for different holographic recording configurations in LiNbO3 ： Fe is presented. All of the magneto-photovohaie tensor elements are tabulated. And the equations of the bulk photovohaic and the magneto-photovoltaie current for four different holographic recording configurations are given. Our results show that the diffraction efficiency of holographic grating depends on the applied magnetic field for each configuration, since the magneto-photorefraetive effect induces a change in the electric current. For different configurations, the influence of the nonlinear effect in LiNbO3 ： Fe induced by the magnetic field is different. A method for measuring certain tensor elements is discussed.
