A circular Airy vortex beam carrying two point vortices symmetrically on the x-axis with the same and opposite signs

We study circular Airy vortex beams (CAVBs) with a pair of point vortices symmetrically loaded on the $x$-axis of initial plane. The two case of the vortices with same and opposite signs are all studied. We only study the relationship between properties of the focal pattern and the loading position parameter (denoted as $d_v$) of the two vortices(so we set the absolute value of topological charges being one.) Good agreements between simulation and experiments have been achieved. We reasonably explains the behaviour of the focal pattern as $d_v$ increases from small to large enough. The tailoring effect of $d_v$ of the two vortices on the focal pattern may have potential applications in optical micromanipulation, communications and other fields.
