Abstract
In the present study, record and readout of holographic transmission diffraction gratings in photopolymer media are investigated with allowance for an arbitrary degree of nonlinearity of photopolymerization, contrast of interference patterns, and absorption and arbitrary relative contributions of polymerization and diffusion recording mechanisms. A theoretical model of (N + 1) 3-D harmonics of the refractive index grating, based on a solution of the coupled kinetic photopolymerization equations, allows the time dynamics of harmonic amplitudes, 3-D refractive index profile, diffraction efficiency, and angular selectivity of the recorded gratings to be investigated.
