From: Intense vortical-field generation using coherent superposition of multiple vortex beams
Numerical results when the number of the incident sub beams N = 16, 24. The peak intensity \({I}_{0}\) of the sub-beams is set to 1 at the waist plane x = 0. (a), (c) Intensity distributions of the sub-beams at the source plane x = − 4 mm when N = 16, 24, respectively. (b), (d) Intensity distributions of vortex light combined field at the waist plane x = 0, when N = 16, 24, respectively.
