| 摘 要： | 通过耦合波方程的方法，考虑光折变晶体中存在基频光栅和最低阶的高频和组合光栅，本文给出了各种情形下的耦合波方程及其解，结果表明一对相干光束的耦合可以被另一束相干的总光强，相位和调制度等控制，理论上，利用这种效应，可以实现相位－振幅转换及振幅－振幅调制。

Double Two-Wave Mixing with Low Modulation: II. Coupling Theory |
| |
| Abstract: | We theoretically investigate a mixing configuration defined as double two wave mixing, which consists of two sets of two mutually beams interacting with the same photorefractive volume. Coupled wave analysis shows that in certain relationships between the two primary gratings′ wavevectors, the coupling behavior of the two pairs beams will be seriously influenced by the 2 order (2K1 and 2K2) and the cross gratings. |
