摘　　要：本文报导用饱和吸收体 BDN 二氯乙烷溶液(10^(-4)M)有效地实现了连续波再现的四波混频,前向四波混频的实验结果指出由于这种饱和吸收的共振增强作用,使 BDN 的三阶极化率|x^(3)|值比 CS_2高三个数量级。实验研宄了热弛矛光栅和粒子数分市空间光栅二种四波混频机制。In this paper,the experimental investigation results of the nonlinear resonance-enhanced effect in saturable absorber.By using BDN-dicholorothane solution(10^(-4)M),the fourwave mixing with CW reading beam was observed.Forward four wave mixing experimental resultshowed that the measured value of third-order susceptibility |x^((3))|,of BDN was three orders ofmagnitude higher than that of CS_2(liquid state).It was found that both thermal grating andpopulation grating were involved in the four wave mixing process.
