Holographic formation of diffractive optical elements in photopolymer with two-beam interactions taken into account

Abstract

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.
