Off-Axis And Multi Optical Bottles From The Ring Airy Gaussian Vortex Beam With The Astigmatic Phase

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.
