Abstract

A new method for obtaining high-order Bessel light beams has been developed and proved theoretically and experimentally. It is based on the phenomenon of transformation of circularly polarized light beam passing through biaxial crystal along its binormal. The method can provide conversion of input Gaussian beam into Bessel beam with an almost 100% efficiency. Besides this method can be used to convert high-intensity laser beams. The light field having the cross distribution in the form of spiral is obtained from the first order Bessel light beams. A possibility of formation of the zeroth and the first order Bessel light beam from Gaussian light beam in biaxial crystal without axicon is investigated theoretically.
