Optical Trapping of Double-Ring Radially Polarized Beam with Improved Axial Trapping Efficiency
Radially polarized beams, focused by a high numerical aperture (NA) objective, have non-propagating fields along the propagation axis in the focal region, which leads to a higher axial trapping efficiency in comparison with linearly polarized beams. We propose a design for converting a lowest-order...
