在Langmuir-Blodgett膜中实现多重前向光学相位共轭现象的研究

Multi-forward optical phase conjugate wave outputs in Langmuir Blodgelt films

本文报道一种新型的三次非线性光学薄膜——花青一花生酸(OY-AA)复合Langmuir-Blodgett(LB)膜以及采用BOXCARS结构的简并四波混频在LB膜中实现多重前向光学相位其轭波输出的现象.该输出的方法既是一研究介质三次非线性光学性质的有效手段,而且可望在光学图象处理中有着其独特的应用.

A new kind of third-nonlinear optical Langmuir-Blodgett films is reported in this paper, And in which an interesting phenomenon, multiple forwavd optical phase conjugate wave (FPCW) outputs using BOXCABS degenerate four-wave-mixing, technique has been observed, This way to obtain multiple FPCWs is considered as a simple method to inverstigate the third-nonlinearities of thin films and some special applications in optical image processing are expected,
