Abstract

In the work we suppose a mathematical model of 3-dimensional grating spatial profile formation in photopolymer material with light induced optical absorption at polymerization-diffusion processes of holographic recording of transmitted chirped grating. The model is based on kinetics equations of photopolymerisation and diffusion for the zero and the first spatial harmonics of refraction index grating. We have obtained analytical solution of the kinetics equations describing the process of grating profiles transformation during the recording process. The main point of the numerical calculation presented in the paper was examination the possibilities to compensate the non uniformity of the chirped gratings profiles with the help of amplitude profiles of recording beams.
