摘要
研究了甲基橙 (MO)偶氮染料掺杂聚乙烯醇 (PVA)薄膜的光致双折射和全息光存储特性 利用YAG激光二倍频 ( 5 32nm)作为写入光 ,He Ne激光 ( 632 .8nm)作为读出光 ,考察了不同染料浓度薄膜的光致双折射 ,探讨了光致双折射和泵浦光功率的关系 ,并实现了全息光存储
The photoinduced birefringence and holographic storage in methyl orange dyes (MO) doped polyvinyl alcohol (PVA) films were reported.The relationship between the photoinduced birefringence and the dye content and pumping power were investigated by using the writing light of 532 nm and the reading light of 632.8nm.The holographic experiments were carried out in these media.The physical mechanism of the optical storage in MO/PVA was elucidated.
