| 摘 要： | 用前向二波耦合实验方法，对几种掺杂的LiNbO3晶体的光折变性质中出现的光伏现象进行了研究。在双掺杂的Ce：Fe：LiNbO3晶体中得到强纵向光伏效应，该效应可以对衍射效率产生59．7％的调制；在单掺杂的Ce：LiNbO3和Zn：LiNbO3等晶体中，得到由横向光伏效应产生的偏振态记录光栅。 |

| Abstract: | In the experiment of two-wave mixing, the photovoltaic effect on photorefractive property was studied in some doped LiNbO 3 crystals. Strong lognitudinal photovoltaic effect can be got in Ce: Fe: LiNbO 3, which can modulate the diffraction efficiency at the rate of 59.7%; grating of polarization records was also made in Ce: LiNbO 3 and Zn: LiNbO 3 crystal, due to the transverse photovoltaic effect. |
| Keywords: | information optics LiNbO3 crystals photorefractive photovoltaic effect two-wave mixing |
