| 摘 要： | 光折变晶体中二波耦合过程也是全息记录的过程,本文将描述二波耦合的耦合波方程与描述光折变全息的Kukhtarev方程联立,基于Moharam的场函数,以光强调制度为主要变量,求得了适用于任意的干涉光强调制度及任意常量光激发效率下的耦合的两束光波在稳态时的解,进而得出热激发对光波耦合的影响。

| Abstract: | Based on the Kukhtarev’s model and the Moharam’s field function exact steady state analytic expressions for dynamic two-beam coupling are deduced for any constant values of light modulation depth and light excitation efficiency.Further the influence of the thermal excitation is considered. |
