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.
