摘要
减小Ｃｅ：Ｆｅ：ＬｉＮｂＯ３晶片的厚度，扩大泵浦光束直径，由于光爬行效应晶体产生衍射自增强。单光束辐照Ｃｅ：Ｆｅ：ＬｉＮｂＯ３晶体时，出现变偏振现象（ｏ光变ｅ光，ｅ光变ｏ光）等各向异性自衍射。本文对上述现象的形成机理进行了探讨。
The self-enhancement of diffraction was obtained due to the light crawling effect by reducing the thickness of the Ce: Fe: LiNbO3 and by increasing the diameter of the pump beam. Lighting the crystal by a single beam, the phenomera of variation of the light polarization, i. e. the anisotropy self-diffraction from o-light to e-light or from elight to o-light were observed, and the machenism was discussed.
