Holographic recording in nanoparticle-doped photopolymer

Abstract

A nanoparticle-doped acrylic photopolymer is characterised as a material for holographic recording. The influence of nanoparticles on the photopolymer dynamic range, dynamics of recording, temporal stability and mechanical stability in terms of shrinkage has been studied. The dynamics of recording and the temporal stability are investigated by real time monitoring of the build up of diffraction gratings of spatial frequencies of 200 to 2000 1/mm. The shrinkage has been characterised by recording slanted transmission gratings and observation of the change in the Bragg angle.
