摘要
研究向列型液晶中由光致分子重取向引起的简并四波混频光学相位共轭现象 ,着重讨论液晶薄膜厚度 d、探测光与一泵浦光之间的夹角θω 以及光的入射面和液晶指向矢之间的夹角β对相位共轭光产生效率的影响 .
The phase conjugation by degenerate four wave mixing (DFWM) due to optically induced mloecular reorientation in nematic liquid crystals (NLC) films are presented.The dependences of the phase conjugation efficiency on the parameters including the NLC film thickness d,the intersecting angle θ ω between the pump and the probe beams,and the angle β between the plane of the incident beams and the nematic director are mainly discussed.
