Coherent beam combining of optical vortices [PDF]
We experimentally demonstrate the power scaling of optical vortices by the coherent beam combining, encompassing topological charges ranging from l=1 to l=5 realized on the basis of a Yb-doped fiber short-pulsed laser system. The combining efficiency varies from 83.2 to 96.9% depending on the topological charge and beam pattern quality generated by the

Dynamic beam shaping with coherent beam combining [PDF]
AbstractCoherent beam combining (CBC) is a method of enhancing laser power. It has recently transitioned to industrial applications, unveiling new possibilities in laser technology. CBC merges multiple laser channels from a single source, controlling their phase to create constructive or destructive interference.

Bessel-Gauss coherently combined beams
The application of a conical wavefront in the near field of the tiled aperture coherent beam combination (CBC) produces a “star-like” Bessel-Gauss irradiance pattern i.e. BG-CBC, in the far field. The properties of such a structured optical field were numerically investigated.
