Radial- and azimuthal-polarization free electron lasers

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1993
Abstract A new free electron laser concept has been developed which is capable of providing high power optical beams with novel polarization states. It is possible to generate azimuthally polarized radiation with properly chosen electron beam and wiggler field parameters.

Switchable High Polarization Purity Radially and Azimuthally Polarized Nd:YAG Microchip Laser

Conference on Lasers and Electro-Optics, 2017
Watt-level switchable high polarization purity radially and azimuthally polarized laser beams have been generated in the Nd:YAG microchip laser pumped with a focused annular-shaped pump beam formed with a hollow focus lens.

Polarization-multiplexed multifocal arrays by a π-phase-step-modulated azimuthally polarized beam

Optics Letters, 2014
We demonstrate a polarization-multiplexed multifocal array capable of individually manipulating the focal polarization state in each focal spot. Breaking the rotational phase symmetry through adding a π-phase-step to an azimuthally polarized beam leads to a linear focal polarization state with high polarization purity. Through the superposition of such

A 1kW azimuthally polarized CO 2 laser

SPIE Proceedings, 2008
An optical resonator for generating high-power, cylindrically polarized beams is demonstrated. The rear mirror of a commercial CO 2 laser is replaced by a novel triple-axicon retroreflector unit that is composed of a waxicon and an axicon accurately fitted together. Selection of the polarization is made by the reflectivity difference between p and s
