摘　　要：介绍了在近代物理实验课中开设甲基橙掺杂聚乙烯醇薄膜的简并四波混频特性的实验设计,论述了实验原理和实验中采用的非线性介质的结构与性能,研究了泵浦光与探测光之间的夹角等实验条件对实验结果的影响,得到了相位共轭光强度与探测光和泵浦光的关系,分析了实验中产生的信号光强度和反射系数的变化及产生这种变化的机制.The experiment about the DFWM properties of polyvinyl alcohol films doped with methyl orange dyes is conducted in modern physics experiments. The experimental scheme is introduced. The principles of the experiment are demonstrated, as well the configuration and characteristics of the nonlinear medium. The influence of the angle between pumping light and probe beam on the experimental results is studied. The intensity of conjugate signals under certain conditions is recorded, and the change and mechanism of the intensity of conjugate signals and reflective coefficient are analyzed.
