Green Laser Photoswitchable Azobenzene Polymers for Rewritable Hologram with High Diffraction Efficiency

Abstract

In order to develop a green laser rewritable hologram material, azobenzene monomers and polymers were synthesized and holographic properties such as diffraction efficiency, rewritability were measured. As a result, it has been found that even if repeated recording and rewriting are performed, the recoding medium is maintained in a stable state and we confirmed that G#-5/95, which has an absorption wavelength more suitable for green laser (532 nm), has higher diffraction efficiency than G-5/95.
