The mechanism for optical storage in these materials has been attributed to a statistical reorientation of the azobenzene chromophors perpendicular to the polarization of the incident electric field of the pump laser beam . the photoinduced birefringence and holographic storage in methyl orange dyes ( mo ) doped polyvinyl alcohol ( pva ) films were reported firstly in this thesis . the relationship between the photoinduced birefringence and the dye content and pumping power was investigated by using the writing light of 532 nm ( double - frequency of nd : yag laser ) and the reading light of 632 . 8 nm 本文研究了甲基橙( mo )偶氮苯染料摻雜聚乙烯醇( pva )薄膜的光致雙折射和全息光存儲特性,利用yag激光2倍頻( 532nm )作為寫入光, he ? ne激光( 632 . 8nm )作為讀出光,研究含有不同染料濃度pva薄膜的光致雙折射特性,探討了光致雙折射和泵浦光功率的關系,實現了全息光存儲,所得光柵生長曲線包含快過程和慢過程,快過程以異構相位光柵的生長為主,慢過程以取向光柵的生長為主,對此實驗結果本文給出了合理的理論解釋。

The photoinduced changes in polarity and molecular structure have led to widespread application of azobenzene derivatives as reversible molecular switch devices 光致極性和分子結構的變化使偶氮衍生物作為可逆的分子開關器件得以普遍應用。
