Linear and Nonlinear Optical Effects in Liquid Crystals

这一提议旨在研究液晶的光学性质如何被外部扰动所改变，在这种情况下是由普通激光束。其中一个有待探索的领域包括激光诱导的分子重定向和宏观结构转变、高度非线性光波传播以及激光诱导的液晶非线性动力学。另一个领域关注的是液晶特性，比如那些由表面或界面过程产生的特性，这是其他技术无法轻易探测到的。

This proposal aims to investigate how the optical properties of liquid crystals are modified by external perturbation, in this case by an ordinary laser beam. One area to be explored involves the study of laser-induced molecular reorientation and macroscopic structural transitions, highly nonlinear optical wave propagation, and laser induced nonlinear dynamics in liquid crystals. Another area focuses on liquid crystal properties, such as those resulting from surface or interface processes, that cannot be as easily probed by other techniques.
