Abstract
In the present paper, the process of formation of holographic diffraction gratings (HDG) in photopolymer materials in transmission and reflection geometry of record by an optical pulse train with duration comparable with characteristic times of the polymerization and diffusion processes is investigated with allowance for light-induced absorption. A solution of the problem of forming HDG with 2D spatially non-uniform amplitude profiles by light beams is derived in the approximation of zero and first harmonics of the monomer concentration and refractive index. 3D spatial distributions of the HDG amplitude profiles are presented in an analytical form of recursion relations.
