摘　　要：合成一种新的推拉型偶氮化合物并将掺入ＰＭＭＡ中制成光学薄膜器件．用Ｚ扫描技术测量了该材料的非线性折射率，用ＤＦＷＭ装置研究了该材料在可见光长波区光存储特性，获得了良好的实时和短时存储信息，存储功率密度小于０．１Ｗ／ｃｍ２．分析了这种非共振吸收区光存储机理．The new push-pull azobenzene compound was synthesized and doped into PMMA films.The nonlinear refractive index of this AD-PMMA film material was measured by the Z-scan technique.The optical storage character was expressed by using the DFWM setup.The excellent real-time and short storage of image information was obtained when He-Ne laser was used as the light source.The minimum writing power was less than 0.1 W/cm2 and the nonresonant storage mechanism was analyzed.
