Paper Abstract

In this paper, a blue-sensitive photopolymer holographic recording material was prepared. The visible-light sensitive photoinitiating system was composed of sensitizer, initiator, hydrogen-donor, monomer and binder. Compound sensitizing as a new method for improving exposure sensitivity of this material was proposed. Experiments results indicate that compound sensitizing significantly increased the exposure sensitivity from about 55mJ/cm2 to 40 mJ/cm2, while without any affection to the maximum obtainable diffraction efficiency. More than 85% of transmission grating diffraction efficiency can be attained as a very simple post process was performed. Mechanisms of polymerization and hologram formation were discussed. The holograms, with a good physical and chemical stability under ambient circumstance, have much potential in optical communication, such as filters and switches.
