Study of Holographic Character of a Novel Photopolymer
新型双染料敏化的宽带光聚物全息特性研究

A novel wide band sensitive holographic recording materials co-sensitized by two dyes is presented. The sensitive spectrum of the polymer is dramatically extended from 50 nm to 200 nm.The maximum diffrcation efficiencies are more than 40% and up to 80% in different exposure wavelengths.Four different images are stored in the same location of the photopolymer film by the multi-wavelength holographic storage method, and these images can be reconstructed with high quality. It is said that this material is suitable for multi-wavelength holographic storage.
