摘要
Abstract A practical method for generating an anomalous Airy vortex beam is proposed, and characteristics of this novel kind beam are investigated. Results show that orbital angular momentum (OAM) quantum number n could be used to modulate the profiles of vortex rings, asymmetric parameter c would cause the beam rotation and phase distortion, and when increase control parameters α and β , more energy would concentrate on the side lobes, and the side lobes in the x-direction and y-direction separately would expand laterally and longitudinally, respectively. Particularly, the position and moving direction of the light spot could be controlled precisely according to the actual needs by altering the phase shift proportional coefficients p and q . Our work would extend potential applications of the mixed vortex beams in optical micro-manipulation and optical trapping.
