Like a whirlpool, a new light-based communication tool carries data in a swift, circular motion. Described in a study published last week by the journal Science, the optics advancement could become a ...

A team has been developing a new type of laser-induced forward transfer (LIFT) for laser printing using an optical vortex, which has been dubbed OV-LIFT. The team succeeded in printing crystals with ...

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 ...

Researchers have succeeded in printing uniformly sized droplets with a diameter of approximately 100 µm using a liquid film of fluorescent ink. This ink, with a viscosity roughly 100 times that of ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...
