Abstract
The formation of holographic transmission and reflection gratings is examined taking into consideration photoinduced absorption in photopolymer materials. The holographic gratings are assumed to be formed by light beams with arbitrary amplitude profiles. The problem is solved analytically in the zero-and first-harmonic approximation of the monomer concentration and refractive index with allowance for the interference-pattern contrast, an arbitrary degree of photopolymerization nonlinearity, and the dependence of the diffusion coefficient on the degree of polymerization. The effect of beam-amplitude profiles and light-induced absorption on the spatial profiles of holographic gratings is studied using numerical simulation. The effect of light-induced absorption on the diffraction characteristics of holographic gratings is discussed.
