Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...

Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular momentum, have spiral wavefronts and ring-shaped intensity ...

In recent years, optical vortices have attracted extensive attention in laser advanced manufacturing because of their annual intensity distribution and orbital angular momentum. Compared with the ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...
