摘要
报道了在ｃ向切割ＬｉＮｂＯ＿３：Ｆｅ晶体薄片的前向光散射中观察到的一种新的类似鸭蛋形的各向异性衍射光环图样，并且提出了由入射光、强的背向散射光而引起的四波混频各向异性光散射机制，圆满地解释了有关实验结果。
new kind of anisotropic photorefractive light-induced diffracted ring pattern──ovallike pattern in c-cut LiNbO_3:Fe crystal sheet is observed and a mechanism of four-wave mixing induced by the incident light and its stroog backward scattered light is proposed to explain the experimental results.
