Abstract

The holographic characteristics of two different photopolymer films containing methyl violet dyes in polyvinyl alcohol matrices were examined. One of the films contains only dye in the matrix. A holographic grating in the film is created by bleaching the dye. The other film contains acrylamide as a monomer and triethanolamine as a promoter as well as dye in the matrix, and a holographic grating is formed by the photopolymerization of acrylamide. In this study, the temporal evolution of diffraction efficiency was measured during holographic recording, by changing the dye concentration, exposure power, etc. For the film exposed to bleaching, the diffraction efficiency had a peak at a specific exposure time, and then decreased with overexposure. For the film exposed to photopolymerization, the diffraction efficiency was saturated at high exposure, and the maximum efficiency was approximately 40%, much higher than that of the other film.
