A photopolymer material sensitized by acridine orange for holographic storage

We prepared a photopolymer material sensitized by acridine orange for high-density holographic storage. The absorption peak of this sample is near 490nm, which is especially appropriate for using 488nm exposure wavelength of Ar + laser for holographic recording. We illuminated it with three exposure wavelengths (476nm, 488nm and 496nm) and the experimental results show that the maximum diffraction efficiency is 52%. Some holograms stored in this medium can be reconstructed clearly. It is found that this photopolymer is appropriate for high-density volume holographic storage.
