    Abstract

    Three-dimensional (3D) intensity distribution of double zero-order Bessel beams is theoretically analyzed and simulated in computer. It is found that a chain of three-dimensional localized hollow beams can be generated by interference of the double zero-order Bessel beams. Dependence of the size, the spatial period and the quality of these localized hollow beams on the parameters of the double zero-order Bessel beams are discussed quantitatively. The condition for zero intensity at the central points of the localized hollow beams is given. We also found that the optimal localized hollow beams can be generated only when the radial ratio of the inner to outer rings is taken as a special value. This research is significant for design of new diffractive optical elements to generate localized hollow beams based on interference of the double zero-order Bessel beams.
