Rotating full poincare beams

We demonstrate numerically the existence and dynamical properties of rotating full Poincare beams (RFP) generated spontaneously or by injection in an isotropic laser which contains no selective elements except circular diaphragm that controls the Fresnel number of the cavity. For moderate Fresnel numbers, we found different kinds of RFP beams each having axially symmetric intensity profiles and distinct structures of polarization topological defects (points of circular polarization and lines of linear polarization).
