摘　　要：Riboflavin is employed as the photosensitizer of a novel photopolymer material for holographic recording. This material has a broad absorption spectrum range （more than 200nm） due to the addition of this dye. The experimental results show that our material has high diffraction efficiency and large refractive index modulation. The maximum diffraction efficiency of the photopolymer is about 56%. The digital data pages are stored in this medium and the reconstructed data page has a good fidelity, with the bit-error-ratio of about 1.8 × 10^-4. It is found that the photopolymer material is suitable for high-density volume holographic digital storage.Riboflavin is employed as the photosensitizer of a novel photopolymer material for holographic recording.
