Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two fundamental limitations have restricted their broader impact: generating large numbers of vortices simu ltaneously and achieving high peak power in such configurations. Until now, large vortex arrays have been limited to low-power systems, whereas high-power demonstrations have typically involved only single vortices. ...read more read less
