Abstract
This work presents the theoretical model of holographic formation of the diffraction optical element (DOE) in photopolymer material (PPM). DOE allows transforming Gaussian light fields to Bessel-like. Self-diffraction of writing light beams at low contrasts is taken into account. It is experimentally shown that influence of effect of self-diffraction in areas of low contrast leads to amplification of level of side’s maxima of diffracted light beam.
