摘要
用一种模型对两波耦合进行了分析，导出了强度和相位的解析式。对影响两波耦合的参数进行了理论分析。分析了对ＢａＴｉＯ３光折变晶体的两波耦合的测量结果。
The analytical expression for the intensity and phase through two wave coupling in photorefractive crystal is deduced with a simple model. The effect of parameters on the two wave mixing was analyzed theoretically. The experimental data of two wave mixing in BaTiO 3 crystal are discussed.
