title: Generation of a radially polarized light beam using internal conical diffraction.
abstract: Using a combination of internal conical diffraction and Mach-Zehnder interferometry we have theoretically and experimentally demonstrated an efficient new technique for the conversion of a linearly polarized Gaussian laser beam to one with radial polarization. These methods that can be adapted to yield either ring-shaped or first order Bessel beams which are radially polarized.
