| Abstract: | 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. |
| Keywords: | two-wave coupling steady-state coupling coefficient recording angle |
