| Abstract: | In this paper, by using the stationary-phase method the propagation properties of diffraction-free beams are analyzed in detail and compared with those of Gaussian beams. An axicon i3 used tOproduce the zeroth-order Bessel beam and then its propagation properties are studied experimentally. Theresults are consistent with the theoretical prediction. |
