Using a vector Fresnel diffraction propagator we investigate the far-field distributions obtained from guided annular modes with different polarization states. Furthermore we demonstrate that a pure azimuthal polarization transforms into a mainly radial one in the propagation of annular beams with azimuthal mode number higher than 0. This property could enhance the performance of a laser metal-cutting system based on these kind of beams.
