摘　　要：耦合波理论是分析光折变晶体的基本方法,针对Cu:KNSBN晶体中双光束耦合稳态耦合增益系数的角度选择性,利用耦合波理论做了分析,结果表明对于一定厚度的Cu:KNSBN晶体,双光束耦合的稳态耦合增益系数具有角度选择性.同时,对于这个结论进行了相应的实验研究,实验结果和理论分析基本吻合.The coupled wave theory is the basic method, it is used to study the angle selection of Cu ： KNSBN＇s steady-state coupling coefficient, the result shows that ,for a certain thickness, Cu：KNSBN has a max angle according to a steady-state coupling coefficient, at the same time, it is also studied by experimet , the result shows that the experiment＇s conclusion is same as the theory＇s.
