摘　　要：报道了一种新型的对绿光敏感的光致聚合物材料。该材料以丙烯酰胺为单体,由光引发剂、共引发剂、成膜物等组成。本材料记录的全息图衍射效率可达50％以上,对材料中染料浓度的优化实验发现其有一个最佳值。在光聚物介质上能够记录信噪比较高的图像。说明该材料适合于大容量体全息存储。A new acrylamide-based photopolymer sensitive to green light is reported in this paper. This material is composed of monomer, crosslinker, photoinitiator, coinitiator, and polymeric film-forming binder. Holographic diffraction efficiency as high as 50% can be attained. The best dye concentration is gotten by optimization of material's composition. A hologram can be stored in this photopolymer and the image can be reconstructed clearly. So this photopolymer is promising to high-density holographic recording.
