Abstract

A novel photopolymer system, which is capable of producing high diffraction efficiency in volume phase holograms, is reported. This photopolymer system consists primarily of bisphenol-type epoxy resin and radically polymerizable aliphatic monomer with diphenyliodonium salt and 3,3'-carbonylbis (7-diethylaminocoumarin) as a complex initiator. The chemistry of imaging formation is based on the radical polymerization of the monomer initiated by a holographic exposure, followed by the cationic polymerization of epoxy resin by heat treatment. Then, radical species and cations are provided through a photocomposition of diphenyliodonium salt.
