Nonlinear optical effects of organic materials have recenty attracted much attention because these materials have a strong potential to change wave length of laser beam into a half or one third. This effect is going to play a very important role in the optelectronic age in near future. We have been studying on new polymer and organic materials showing strong nonlenear optical effects for two years.During this research period we have elucidated relationship between structure and optical nonlinearity and developed new polymer and organic materials based on our theory. The results are as follows.1. The relationship between third harmonic generation (THG) and organic structure have been elucidated theoretically.2. According to the theory, we have found that a series of poly(diolefine) compounds showed strong THG.3. Optical damage of poly(diolefine) (DSP) suffers only very high intensity laser beam which is one order of magnitude higher than that of KDP.4. Calcone delivatives shows very strong SHG. The activity is 8 times begger than that of LINb <O_3> which is highest among inorganic materials.

有机材料的非线性光学效应最近引起了人们的广泛关注，因为这些材料具有将激光束波长改变一半或三分之一的强大潜力。这种效应将在不久的将来的光电子时代发挥非常重要的作用。我们对具有强非线性光学效应的新型聚合物和有机材料进行了两年的研究。在这个研究期间，我们阐明了结构与光学非线性之间的关系，并根据我们的理论开发了新型聚合物和有机材料。结果如下： 1．从理论上阐明了三次谐波产生(THG)与有机结构之间的关系。 2．根据该理论，我们发现一系列聚二烯化合物表现出较强的THG。3。聚二烯(DSP)仅受到非常高强度的激光束的光学损伤，比KDP.4高一个数量级。 Calcone 衍生物显示出非常强的 SHG。其活性比无机材料中最高的LINb<O_3>高8倍。
