摘要
有机光折变(PR)材料是一种新型功能材料。该类材料近几年倍受关注,并取得了可喜成果,已合成出一些具有高衍射率、光放大系数及适合光学窗口的材料。本文综述了近期PR聚合物的研究现状,着重介绍它们的一些光学性能(双光耦合系数和衍射率),并对其研究所遇困难及发展趋势进行了分析。
Organic Photorefractrive (PR) material is a new kindof nonlinear optical material. A lot of researches focus on this field and considerable progresses have been made. We review the present progress on PR polymer and emphase on their optic property such as two beam coupling coefficient and four wave mixing diffraction efficiency. Some problems and spectacles in this field was also discussed.
