摘要: 本文研究了导电聚合物的三阶非线性光学极化,分析了提高非线性系数的物理因素。对于三次谐波产生系数得到了与实验一致的结果。
Abstract: The third order optical nonlinearity in 1-d conducting polymers are investigated with a simple model. The relevant physical effects on the nonlinear polarization are analysed. For third harmonic generation our result is in good accordance with the experiment of prestine polyacetylene.
