Formation of two-dimensional photopolymer diffractive optical elements for converting light beams with two-beam interactions taken into account

Abstract

Abstract Bessel light beams are used in many fields, such as nonlinear optics, optical metrology, design of atmospheric wireless telecommunication lines, nanoscale objects manipulating, etc. Bessel beams do not diffract, they have restoration properties, they retain high intensity in the axial region at large distances. Thus, the search for an affordable method of forming such beams seems very relevant. In this paper, we study the process of two-dimensional diffractive optical elements (DOEs) holographic formation in photopolymer materials (PPM) with allowance for two-beam interactions. DOEs is intended for converting light beams with a Gaussian distribution into a Bessel-like ones.
