Work done on the optimization of a photopolymer holographic recording material is presented. The material consists of a PVA (polyvinylalcohol) binder, a monomer, a crosslinking monomer, an electron donor and a dye sensitizer which renders the material suitable for recording in the 633 nm spectral region. Diffraction gratings were recorded with approximately 80% diffraction efficiency with the optimized system. By changing the relative concentrations of the components in the material, sensitivity was improved by a factor of 5. Total light power remained at approximately 5.5 mW for recording.
