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 of topological charges and spatial location of vortex pairs on abrupt autofocusing behaviour of a CAPB with vortex pairs are evaluated by numerical simulations. https://www.prepobsessedes.shop/product-category/tanks/
