Focus shaping of cylindrically polarized vortex beams (CPVBs) by linear axicon is studied theoretically. Vector diffraction theory has been used to derive the expressions of the light field in the focal region. It is shown that a different intensity

Double focal spots have been generated in the focal region of annular axicon by focusing azimuthally polarized double-ring-shaped (APDRS) beam. Our results indicate that the properties of twin spots are affected by axicon and beam parameters.

Focusing properties of a radially polarized double-ring-shaped beam with an annular classical axicon are numerically investigated based on vector Debye theory. Double focal spots and a flat-topped beam can be generated by choosing appropriate values
