Abstract
In the work an analytical model of transmission holographic grating formation by light beams with non-uniform phase-amplitude profiles is presented The model takes into consideration influence of light absorption of a photopolymer with dye-sensitizer and nonlinearity of photo-polymerization on the spatial profiles and diffraction properties of the chirped grating. The model of diffraction efficiency and selective properties of chirped gratings is also presented. The results of fitting experimental data and numerical ones are shown and discussed.
