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

Soliton algebra by vortex-beam splitting
Optics Letters, 2001 We experimentally demonstrate the possibility of breaking up intense vortex light beams into stable and controllable sets of parametric solitons. We report observations performed in seeded second-harmonic generation, but the scheme can be extended to all parametric processes.
