An all-fiber Raman laser for cylindrical vector beam generation

, 2022
Art. 125108, 8 S.We demonstrate a compact Raman all-fiber oscillator for cylindrical vector beam generation. The laser is based on a strongly guiding passive fiber with two fiber Bragg gratings inscribed in it, which separates the different transverse ...

Beam quality measure for vector beams

, 2016
Vector beams have found a myriad of applications, from laser materials processing to microscopy, and are now easily produced in the laboratory. They are usually differentiated from scalar beams by qualitative measures, for example, visual inspection of ...

Scattering of cylindrical vector beams by a multilayered sphere

, 2014
The scattering of a cylindrical vector beam by a multilay-ered sphere is investigated. An analytical formula for thecalculation of beam shape coefficients of a cylindrical vec-tor beam is first derived using Integral Localized Approx-imation.

Energy rule for enhancing the spin Hall effect in superposition of axisymmetric beams with cylindrical and linear polarization

Компьютерная оптика
We study the spin angular momentum of a superposition of two vector light beams radial symmetry, one has cylindrical polarization and another – linear. Both beams can have an arbitrary radial shape.
