AI Technical Summary
Existing photopolymer holographic recording media suffer from low photosensitivity and unstable holographic performance, especially due to large grating offset caused by slow polymerization rate and high volume shrinkage.
Using epoxy resin and various polymerizable monomers as writing monomers, the polymerization rate is increased and the volume shrinkage is reduced through the ring-opening of epoxy resin and the covalent bond formation of polymerizable monomers. Combined with components such as photoinitiators, chain transfer agents and catalysts, a highly efficient holographic recording medium is formed.
A photopolymer-type holographic recording medium with high photosensitivity and stable holographic performance has been achieved, featuring low exposure, high diffraction efficiency, and excellent holographic performance.
