甲酚紫非线性光学性质的研究

Nonlinear optical property of cresyl violet

报道了甲酚紫染料的非线性光学性质的实验研究方法及其结果.利用简并四波混频技术,测量得到甲酚紫甲醇溶液(浓度为5×10^(-4)M)的三阶非线性极化率X^(3)为2.0×10^(-10)esu.此外,利用不同强度皮秒脉冲相关技术得到了甲酚紫甲醇溶液的吸收恢复时间τ_(21)为163ps.

This paper studies the nonlinear property of cresyl violet. By using degenerate four-wave mixing, the 3rd nonlinear electric susceptibility X(3) = 2. 0 × 10~10esu have been obtained. Afterwards,its relaxation time was measured as τ21 =163 ps,by using pulse correlation technique.
