This paper is devoted to recording of a periodic lattice in the photopolymerized nanocomposite with nanoparticles of nonlinear optical DAST crystal (4-dimethylamino-N-methyl-4-stilbazolium tosylate) by holographic method. Nanocomposite consists of the mixture of two monomers: IDA (Isodecyl acrylate) and TMP (Trimethylolpropane ethoxylate (1 EO/OH) methyl ether diacrylate) with molecules of DAST dissolved in methanol. Initiator In2 (2,2-Dimethoxy-2-phenylacetophenone) provides photopolymerization.At solution centrifugal separation solvent evaporation and crystal formation start. It is shown that there is a record of the volume hologram when two-beam interference is used. Micro photos prove the movement of DAST nanoparticles in volume that provides creation of nonlinear grating, which can be used for quasi-phase matching of nonlinear effects.
