光场与掺杂向列相液晶薄膜相互作用的若干问题

Interaction of the Optical Electric Field with the Doped Nematic Liquid Crystalline Films

从激光与掺杂液晶薄膜相互作用的角度,介绍了掺杂液晶非线性光学的多个不同侧面,阐述了光场诱导液晶分子指向矢的重新取向问题、偶氮物掺杂液晶超大光学非线性问题、以及掺杂液晶光限幅的研究现状和进展。

From the viewpoint of the interaction of light with the doped liquid crystals, this paper presents a number of the important aspects of the doped liquid crystalline nonlinear optics, including the problemof lightinduced liquid crystalline molecular director reorientation, the supra optical nonlinearity me chanism of the azocompound doped liquid crystals, and the stateofthearts and the recent progress in the optical limiting of the dyedoped liquid crystals.
