Propagation of Azimuthally Polarized Bessel-Gaussian Beam through Helical Axicon

Propagation properties of azimuthally polarized Bessel-Gaussian (APBG) beams with non-zero order through a helical axicon (HA) are theoretically investigated. The formula of APBG beams field in the focal region are derived by the vector diffraction theory. Numerical results illustrate that the beam...
