联立稳态带传输方程和耦和波方程,基于Kukhtarev模型和Moharam的场函数,以光强调制度为主要变量,求得了适用于任意干涉光强调制度及光激发效率为任意常数时的光折变晶体中全息相位栅包迹的解析解。在此基础上,分析了非破坏性读出情况下的衍射效率。

Based on the Kukhtarev’s model and the Moharam’s field function exact steady state analytic expressions for dynamic grating envelopes are deduced for any constant values of light modulation depth and light excitation efficiency. Furthermove the diffraction efficiency is considered for nondestructive readout.
