    Abstract

    A novel type of photopolymer holographic recording materials sensitive to red light and green light is presented. The photopolymerizable system comprises two monomers, a photoinitiation system, and an inactive component referred to as a binder. Diffraction efficiencies are no less 30%, and sensitivities are no less 25 cm2/J when exposed to red light and green light respectively. Spatial frequencies of red light ranged from 1600~2800 lp/mm, and the best response spatial frequency is 2274 lp/mm and the corresponding diffraction efficiency is 27.72%. Spatial frequencies of green light ranged from 1700~3000 lp/mm, and the best response spatial frequency is 2335 lp/mm and the corresponding diffraction efficiency is 25.72%. There is no crosstalk among reconstruction images when recording in the same point by red and green light, so the photopolymer is promising to two-wavelength multiplexing holographic storage.
