The use of low-viscosity neutral components for increasing the diffraction efficiency of photopolymer holograms

摘要

The hologram recording in low-viscosity liquid photopolymerizing compositions with a neutral component is studied theoretically and experimentally. A diffusion model of redistribution of the composition components that takes into account the polymer mobility at the initial stage of photopolymerization is proposed. It is shown that the use of methanol as a neutral component significantly increases the diffraction efficiency.
