Abstract
A new red sensitiver holographic recording material has been studied by our group. The composition of the material is as follows: polyvinyl alcohol as binder, acrylamide and methylene bisacrylamide as monomer, methylene blue as sensitizer, triethanolamine as electron donor and other additive reagents. We get the optimum recipe through many tests. By adding other reagents that were designed by us, we obtain a high quality red-sensitive holographic recording material. The diffraction efficiency of transmission holographic grating is up to 95%, when the exposure energy is 3mJ/cm2. The post-processing is simple, the hologram has high diffraction efficiency, high signal-to-noise ratio, and excellent environmental stability.
