Polarization of orbital angular momentum (OAM) carrying Laguerre–Gauss optical vortex beams, consistent with Maxwell’s equations, is discussed, and experimental evidence for it is presented. The experiments reveal several novel features of such beams, including OAM dependent reconstruction of polarization and spatial profile during propagation.
