摘要/Abstract

摘要： 利用Z-scan法,对掺有以偶氮苯作为母体的一个系列推拉型偶氮化合物的有机聚合物薄膜的非线性光学系数进行了测量,实验结果的分析表明,材料的非线性折射率来源于共轭π电子效应.

关键词: Z-scan法, 非线性折射率, 偶氮化合物

Abstract: With Z-scan technique, we have measured nonlinear optical coefficient of organic thin films doped with push-pull azobenzene compounds, Experimental analysis shows that nonlinear refractive index is caused by π-electrons effect.

Key words: nonlinear refractive index, azobenzene compounds, Z-scan
