Topological Charge of Light Fields with a Polarization Singularity
Photonics, 2022 We have studied diverse vector and hybrid light fields, including those with multiple polarization singularities, and have derived relationships for polarization singularity indices based on the familiar Berry formula, which is normally utilized to find ...

Fresnel and Fraunhofer diffraction of a Gaussian beam with several polarization singularities [PDF]
Компьютерная оптика, 2018 Alongside phase singularities (optical vortices), there may be light fields with polarization singularities (PS), i.e. isolated intensity nulls with radial, azimuthal, or radial-azimuthal polarization around them.

Spin angular momentum of Gaussian beams with several polarization singularities
Компьютерная оптика, 2023 We study a paraxial vector Gaussian beam with several polarization singularities located on a circle. Such a beam is superposition of a cylindrically polarized Laguerre-Gaussian beam and a linearly polarized Gaussian beam.

High-power thin-disk lasers emitting beams with axially-symmetric polarizations
Nanophotonics, 2021 We present the intracavity generation of beams with radial polarization at an average output power of 750 W and an optical efficiency of 43% from a continuous wave thin-disk laser. Circular grating waveguide output couplers (GWOC) were used to select the
