| 摘 要： | 本文利用Z扫描测量技术首次对半花菁LB膜的三阶非线性光学特性进行了研究.实验结果表明,LB多层膜中的半花菁分子具有较高的三阶非线性折射率n2=2.0×10-8(esu),这主要是半花菁分子中π电子体系的贡献,并且由于532nm在其Q吸收带内,引起三阶非线性的共振增强效应,实验数据与理论拟合结果符合得很好.半花菁LB膜的三阶非线性的响应时间在30ns以内. |

| Abstract: | In this paper,the third order nonlinear optical properties of hemicyanine were investigated by using Z-scan technique and UV-visible absorption spectrum in Langmuir-Blodgett multilayers The hemicyanine molecules have a high third order nonlinear refraction n2=2.0×10-8 (esu) which contributed to the π-electron system,and nonlinear resonant enhanced effect due to the 32nm within the Q-band of hemicyanine multilayers The experimental data agreed well with the theoretical fit results The response time of the third order nonlinear optical properties of hemicyanine in Langmuir-Blodgett multilayers is less than 30ns. |
| Keywords: | Third order nonlinearity Hemicyanine Langmuir Blodgett multilayers Z scan |
