摘要: 为了研究在低功率连续He-Ne激光条件下亚甲基蓝掺杂聚乙烯醇薄膜简并四波混频的基本特性,采用简并四波混频技术研究了亚甲基蓝掺杂聚乙烯醇的相位共轭光与入射角度、前抽运光和后抽运光的变化关系,以及透射光栅和反射光栅对相位共轭光的影响。在实验中得到了最大的相位共轭反射率为0.27%。所得的结果对研究染料固化在固体基质中的非线性研究是有帮助的。

Abstract: In order to study property of polyvinyl alcohol films doped with methlyene blue under low power continuous-wave laser radiation generated by He-Ne laser,degenerate four-wave mixing(DFWM) was used to study relations of phase-conjugate(PC) signal along with incidence time,forward-pump beams and backward-pump beam.The PC signal influence from induced holographic transmission and reflection gratings were studied.We observed a maximum PC reflectivity of 0.27% in these dye-doped polyvinyl alcohol films.The result of research is helpful in nonlinear effect study in dye-doped solid.
