摘　　要：理论分析指出,用4束光干涉可形成大部分的布拉格光学晶格点阵.实验制作中利用3个光栅对1束平行光进行衍射,进而得到所需的光束偏转角度,并制作出晶格常量在亚微米量级的面心立方的光学晶格结构,晶格常量和计算结果相符.It is shown by theoretical analysis that most of the Bragg lattices can be created by in- terference of four laser beam. Face centered structure was fabricated by parallel light diffracted by three gratings, and the beam deflection angle was obtained. The measured lattice constants were coin- cident well with the calculated values.
