摘要
采用微扰方法，对有机分子膜中分子规则取向所导致的各向异性进行了研究．给出了有机分子膜的二次谐波强度与基频光和倍频光的偏振方向，以及基板的拉膜方向之间关系的理论表达式，并对常见的几种组态进行了讨论和实验研究．
Abstract The
optical anisotropy of organic molecular films induced by molecular reorientation was investigated
by using the perturbation method.We presented theoretical formulae about the dependence of
second harmonic generation (SHG) intensity on the polarization of fundamental beam,SHG beam
and the dipping direction.The experimental studies and discussion were given under some special
conditions.The experimental results agreed well with the theoretical calculation.
