Description
Summary:A new type of off‐axis and multi optical bottle (OB) from an astigmatic‐phase ring Airy Gaussian vortex beam (APRAGVB) propagating in free space is derived numerically. By choosing appropriate parameters, different sizes and amounts of OBs can be obtained. More importantly, when the APRAGVB has the multi optical vortices at different locations, one can generate off‐axis, multi, and complex OBs. It is believed that the results can diversify optical tweezers applications for multi microparticle manipulation. A new type of multi and off‐axis optical bottle from an astigmatic‐phase ring Airy Gaussian vortex beam is demonstrated. The size of these highly operable bottles can be controlled by the vortex topological charge and the astigmatic factor in two degrees. Importantly, off‐axis, multi, and complex optical bottles are formed by beams with off‐axis and multi optical vortices.
