Abstract: Green light sensitive acrylamide-based photopolymer system was prepared. The photo-sensitive medium is composed of monomer, photoinitiator, coinitiator and polymeric film-formingbinder. Diffraction efficiency of the photopolymer as high as 55% could be obtained. The photo-polymer were baked under different temperature. It is found that the refractive modulation increasesas the baking temperature increases. Ten holograms can be stored in this medium using angle multi-plexing technology. It is promising of our material for high-density volume data storage.
