Megawatt light array generates 3,070 phase-coherent optical vortices
In a lab at Osaka University, physicist Yoshiki Nakata and his colleagues fired a pulsed laser through a stack of three passive optical components and watched it shatter into 3,070 tiny, spinning ...
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 ...
