| Abstract: | 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 θω 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. |

| Keywords: | Nematic liquid crystal Degenerate four wave mixing Phase conjugation |
