A laser beam converted to an optical vortex can perform laser-induced forward transfer (LIFT) of ferrite nanoparticles resulting in twisted single crystals corresponding to the rotation of the vortex.

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 ...

A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by “nulling” out the light of the parent star by ...

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 ...
