Different types of this class of beam are studied and compared. In particular, spirally polarized beams are considered. As an example, polarized Bessel-Gauss beams are analyzed in detail.engjournal articlehttp://dx.doi.org/10.1088/1464-4258/10/12/125004http://iopscience.iop.org/open access535Bessel-Gauss BeamsSemiconductor-LaserOptical VorticesVortex BeamPropagationGenerationDiffractionSystemsLawsRodÓptica (Física)2209.19 Óptica Física
