Materials with diffusion amplification for optical-information recording and their study by a holographic method

This paper discusses the principle of the diffusion development of photoinduced (holographic) gratings with the use of photoattached molecules and its use in creating shrink-resistant photosensitive media for volume holography and in studying polymeric materials by a holographic relaxation method. It discusses how the composition, the fabrication method, and the thermal history of the medium affect its properties. It is shown that polymeric photosensitive materials with diffusion amplification fabricated by polymerization methods in mass differ from those made by casting a film from a solution.
