The generation and verification of Bessel-Gaussian beam based on coherent beam combining
Results in Physics, 2020 We propose a method to generate Bessel-Gaussian (BG) beam by Gaussian beam array where beamlets are arranged along a circle. The phase difference between adjacent beamlets is a constant, and the total phase increment is equal to 2πl (l is integer). Based

Experimental investigation in Airy transform of Gaussian beams with optical vortex
Results in Physics, 2021 The Airy transform was first introduced for a Gaussian beam, and the output beam is an Airy beam. When the Gaussian beam is extended to the Gaussian beam with optical vortex, what kind of output beam will be achieved by executing the Airy transformation.

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.
