Popis:	The peculiarities of holographic gratings recording in the thick layers of photopolymer self-processing materials have been investigated. It is shown the main reason of limit of gratings thicknesses and, consequently, their angular selectivity and diffraction efficiency is the dynamic amplification of holographic noises. The maximum diffraction efficiency and angular selectivity with the minimum noises are achieved with use of pre-polymerization of layer and the post-polymerizing self-amplification of holograms. This method allows to fabricate gratings with the thickness up to inmi and angular selectivity about 6'.
