Abrupt autofocusing performance of a circular Airyprime beam with vortex pairs
Abrupt autofocusing performance of a circular Airyprime beam (CAPB) with vortex pairs propagating in free space is investigated.Here the vortex pairs are off-axis by default.The influences gauze fabric by the bolt of topological charges and spatial location of vortex pairs on abrupt autofocusing behaviour of a CAPB with vortex pairs are evaluated b
