Photosensitive monomer and oligomer materials for holographic recording in the visible and near IR

Recording media based on the polymerization of monomers and oligomers commonly used in the Radiation Curing area, appear to be promising materials to record holographic patterns produced by laser sources emitting in the visible and near infrared part of the spectrum. A polymerization takes place only in the bright areas of the interference pattern and volume phase holograms exhibiting high diffraction efficiencies which can be viewed immediately after exposure, are created. Several examples of monophotonic and biphotonic systems will be discussed and presented.
