摘要
合成了一种新的推拉型偶氮化合物并将其掺入聚甲基丙烯酸甲脂（ＰＭＭＡ）中制成光学薄膜器件，用其实现了非共振区的可见光长波段光存储，获得了良好的实时和长时存储的图象信息。存储功率密度小于０．１ｗ／ｃｍ２。文中还分析了这种在非共振吸收区的光存储机理。
new push-pull azobenzene compound has been synthesized by diazocupling reaction, and the nonresonant longer wavelength optical storage of the azobenzene compound doped PMMA film was Performed. The excellent real-time and longer storage of image information are obtained when He-Ne laser is used as light source. The minimum writing Power is less than 0. I w/cm2. The nonresonant storage mechanism is analyzed in this paper.
