Abstract
We reveal that polymerization degree is a significant factor that affects the holographic properties of glass-like photopolymer. By modulating polymerization degree, as well as changing the photosensitizer concentration, we fabricate multilayer PQ/PMMA photopolymer, exhibiting excellent performances in storage fidelity and reproduction resolution. A reflection geometry holographic disk system is established using the multilayer sample, in which a high storage density of 40.5GB/cm3 is realized. The reproduced images exhibit high quality with an average diffraction efficiency of 7.4 × 10−4 and average peak SNR of 27.4. This study provides a paradigm for the fabrication and holographic application of other photopolymers.
