Focusing of Laguerre–Gaussian beams by axicon

A simple analytic expression describing the field of various orders of Bessel light beams produced by an axicon is obtained. The focusing properties of an axicon are discussed. The focal length of an axicon as well as the depth of focus for various orders of Bessel beams are determined.
