Refractive Bi-Conic Axicon (Volcone) for Polarization Conversion of Monochromatic Radiation
A new element is proposed for producing an azimuthally polarized beam with a vortex phase dependence. The element is formed by two conical surfaces in such a way that the optical element resembles a mountain with a crater on top, like a volcano (volcanic cone is volcone). The element in the form of...
