Paper Abstract

We recorded reflection holographic gratings in thick photopolymeric films composed of Eosin (as sensitizer) mixed with acrylamide (as monomer), N,N'-methylenebisacrylamide as cross-linking monomer and Triethanolamine (as coinitiator), all dissolved in a polyvinylalcohol host matrix. The gratings were recorded using argon-ion laser at 514.5 nm. By optimization of all photopolymer compositions, we obtained diffraction efficiency as high as 17 % at high spatial frequency of 4800 lines/mm. A comparison was made by replacing Eosin with Rose Bengal in the photopolymer. 10 % shrinkage was measured in both systems.
