This invention provides a process for producing a transparent optical medium consisting of a liquid crystalline polymer which exhibits third order nonlinear optical response. Illustrative of an invention optical medium is a transparent film of a side chain liquid crystalline polymer corresponding to the formula: ##STR1## The transparent film has an isotropic molecular configuration with macroscopic centrosymmetry, and exhibits essentially no scattering of a transmitted incident light beam.
本发明提供了一种制备液晶聚合物透明光学介质的方法,其具有三阶非线性光学响应。该发明的光学介质示例是一种侧链液晶聚合物的透明薄膜,其对应的
化学式为:##STR1## 透明薄膜具有各向同性的分子构型和宏观中心对称性,并且基本上不会散射透射入的光束。
