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 ...

Recent advances in femtosecond optical vortices (FOVs)—characterized by helical wavefronts and high peak power—have enabled breakthroughs in attosecond vortex generation and 3D chiral microfabrication ...

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 ...

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 ...

As a new degree of freedom, the orbital angular momentum of electromagnetic waves exceeds the traditional frequency, phase, and amplitude, and is expected to promote the infinite expansion of channel ...

A project at Finland's Tampere University has secured €4.4 million in funding to further its research into optical vortices. The High-Power Optical Vortices (HiPOVor) project will train 15 doctoral ...
