摘　　要：报道一种测量LiNbO3∶Fe单轴晶体光学不均匀性及其生长层的简便方法 ,由o—e光点间的距离随入射光束在晶体中位置的变化可以计算出晶体不同位置的Δne 的变化 。A simple method for measuring the optical non-homogeneity and growth layers in the LiNbO3 : Fe crystal is reported. We can compute the change of refractive index Deltan(e) at different positions in the crystal according to the distance between e-o light-spots, which vary with the change of the position of incident light-spot in crystal. Furthermore we can obtain the non-homogeneity and determine the position and thickness of the growth layers in the crystal.
