Generation of Perfect 3D Dark Spots Using Double-ring Cylindrical Vector Vortex Beams
A 3D dark spot is generated by using a double-ring-shaped cylindrical vector vortex beam which can be considered as a vector superposition of a double-ring-shaped radially-polarized light and a double-ring-ring-shaped azimuthally-polarized light.The volume of the 3D dark spot generated is very small and the light wall surrounding the dark spot is very uniform.This 3D dark spot is very perfect for particle trapping and for super-resolution fluorescence microscopy.
