摘要
基于场关联原理,采用非相干光时延四波混频法研究了瑞利增强非简并四波混频的时域特性.利用二阶场关联函数理论揭示出混频信号在时域的细微变化,发现信号展示出时域不对称性并且在τ<0时会出现振荡结构,而这种时域不对称性反映了该三阶非线性极化过程的特点.
The theoretical analysis based on Rayleigy-Enhanced nondegenerate four wave mixing provides the closed-form solution for the signal. The temporal behavior of the RENDFWM has been investigated which reveals the characteristics of driven exciting resulted from material response to optical field. The resonant signal shows asymmetric temporal behavior and oscillation structure when τ〈0.
