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 ...

An artistic pressions of a vortex-ring street analog to the structure of magnetic field of a NDSTP, where the right- and left- handed vortex rings were highlighted by blue and red, respectively.

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 ...
