| 摘 要： | 报道了甲基橙偶氮染料掺杂的聚乙烯醇薄膜材料在Ａｒ＾＋激光４８８．０ｎｍ线辐照下，用正交线偏振的６３２．８ｎｍ光作为写入光，通过旋转样品，在同一光斑内形成多个取向不同的相位光栅，实现了多重全息存贮的实验结果。在三重图象的存贮中，通过控制每次的写入时间、得到了三个均匀明亮的衍射图像，其平均衍射效率为０．１％。

| Abstract: | We realized hologram storage within 0.07 cm 2 light spot in thin layers of polyvinyl alcohol (PVA) matrices doped with methyl orange dyes (MO), pre irradiated by the 488.0 nm line of an Ar ion laser using two orthogonal linear polarized 632.8 nm light beams. By rotating sample, multi hologram storage was achieved. By controlling writing time, three hologram images have been recorded in the same light spot. The mechanism of the multiple hologram storage in MO/PVA thin film was discussed using a four energy level model of MO molecular in PVA materices. |
