Segmented vortex wavefront coherent beam combining

A concept of a coherent beam combining with a segmented vortex wavefront (V-CBC) was proposed to generate a dark optical trap. Three-dimensional (3D) irradiance distributions in the caustics of V-CBC were modeled. The properties of the V-CBC were compared with those of the classical vortex beams. The impact of random phase disturbances on the V-CBC was preliminarily analyzed. (C) 2022 Author(s).
