Methylene blue sensitized poly(methyl methacrylate) prepared by the process of dye diffusion has been shown to be efficient medium for recording interference gratings. Phase and/or amplitude holograms can be written in the methylene blue sensitized films of poly(methyl methacrylate) using a conventional source of light a He-Ne laser operating at 632.8 nm wavelength. Kinetics of photobleaching process of methylene blue is measured. Diffraction efficiencies of up to 30% were found for thick holograms. Phase conjugation and multiple holograms writing has been tested in the studied system.
