| 摘 要： | 本文研究了激光同染料液晶的非线性光学效应。理论分析了激光在染料液晶中的传输过程,分别计算了当入射激光功率为10mW/cm2和50mW/cm2时的输出激光光强分布。实验测量了532nm连续激光通过染料液晶传输后的光限幅曲线,观察了输出激光光斑形状随入射激光光强的变化,实验结果与计算结果基本相吻合。

| Abstract: | The nonlinear optical properties of dyedoped liquid crystals induced by 532 nm laser was discussed.The characteristics of laser tranmitted from dye-doped liquid crystals was analyzed.The radial intensity distribution of laser beam was calculated as input laser intensity as 10mW/cm~2 and 50mW/cm~2.Optical limiting behaviors of dye-doped liquid crystals was tested and the far-field beam intensity distribution was observed.Experimental data is good agreement with the calculation results. |
