Holographic photopolymer in hybrid sol-gel matrix

The investigation of the casting and properties of the holographic photopolymer material in hybrid organic-inorganic binder with thickness 0.4-1 mm is described. The hybrid matrix formation was carried out by synthesis of N-vinylpyrrolidone vyniltriethoxysilane co-polymer and subsequent hydrolytic condensation of this co-polymer with tetraethoxysilane pre-sol. It is shown the possibility of formation of stable to crack the solid volume hybrid matrix at ratio pre-sol:co-polymer 1:4. Recording of transient and reflection holograms in hybrid 0.46 mm thickness photopolymer material was carried out. Angle selectivity of the transient hologram was 0.17 degrees and shrinkage of material, measured by changing of Bragg condition of transient hologram didn't exceed 0.7%. The obtained holographic properties were improved on the order of value in comparison with photopolymer material in organic polymer binder.
