Green Laser-sensitized Epoxy Resin Photopolymer Holographic Storage Materials Based on A Two-chemistry System
A green laser-sensitized epoxy resin photopolymer holographic storage material based on a two-chemistry system is prepared. The high optical transparency of photopolymer film is got by designing low refractive epoxy resin matrix system and high refractive write-in monomer system properly. When film thickness is 219 m
the maximum diffraction efficiency is 84.3%
the sensitivity is 5.7410
-3
cm
2
/mJ
the maximum refractive index modulation is 8.6910
-4
and volume shrinkage is 0.32%. An experiment was demonstrated
in which the epoxy resin photopolymer material was used as the shooting of a reflection hologram on coin.It indicates that such material has a resolution of up to 5 000 lp/mm.
