摘要
以多个两波耦合（ＴＷＭ）相位栅模型建立了考虑光扇开效应后的动态两波耦合方程。通过数值求解揭示了在大信号下两波耦合对光扇开效应的抑制作用和在小信号下光束扇开损耗对两波耦合影响的规律。并进行了相应的实验研究。
The dynamic equations of the photorefractive two wave mixing (TWM), which accout on the beam fanning effect, are derived and solved by numerical method. The suppress effect of TWM upon the incident beam fanning in large signal is presented and the effect of the beam fanning on the output of the signal are discussed theoretically. Some relevent experimental investigation is conducted.
