摘要: 用Z扫描方法测量了系列羟基苯基卟啉化合物的非线性折射率n2和反饱和吸收系数β, 由此算出了三阶非线性极化率χ(3), 并分析了分子结构对其三阶非线性光学性质的影响. 实验结果表明, 它们具有大的反饱和系数和三阶非线性折射率, 并且取代基数目和取代位置对实验结果有明显的影响.

Abstract: The nonlinear refraction indices n2 and the reverse saturation absorption (RSA) coefficients β of a series of hydroxylphenyl porphyrins were measured by means of single beam Z-scan technique with a 8 ns laser pulse at 532 nm from which third-order nonlinear susceptibilities χ(3) of the samples were calculated. The hydroxylphenyl porphyrins have a large value of the reverse saturation absorption and a large cubic nonlinear refractivity. The effects of molecular structures on the third-order nonlinear optical properties were discussed. The experimental results show that the effects of different numbers and different positions of the substituents on the nonlinear refractivity of the porphyrins are evident.

Key words: porphyrin, hydroxyphenyl porphyrin, Z-scan, third-order nonlinearity
