This could enable new tech for controlling light with light, opening doors to advanced fabrication, imaging, and illumination ...

The technique works because the green laser (wavelength 532 nanometers) changes the way the crystal responds to some other ...

Laser beams have been shown to cast shadows, defying previous notions that light cannot block light. This phenomenon, ...

"Laser light casting a shadow was previously thought impossible since light usually passes through other light without ...

Conventional knowledge presupposes that if two light beams cross, nothing of note happens. But in an experiment, as detailed ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, scientists decided to experiment in real life — and found that laser beams ...

Shadows are a natural consequence of opaque walls in an illuminated Universe. Light shines; photons travel until they hit an ...

The future of transmitting massive amounts of data digitally may be here, thanks to new technology that uses a "hurricane" of ...

The discovery, centred around controlling tiny hurricanes of light and electromagnetic fields, could revolutionise how much information we can deliver over cables.

WASHINGTON - Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a ...

In a recent study, researchers from the University of Ottawa have demonstrated a remarkable new phenomenon: a laser beam ...
