In a new study, researchers at Osaka University have created the world's first compact, tunable-wavelength blue semiconductor ...

After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, ...

Can light itself, perhaps from a laser, cast a shadow? It might seem like a trick question, but the answer to this is "yes." ...

Scientists have shown that laser light, under certain conditions, can behave like an object and cast a shadow.

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

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out ...

Abrahao from Brookhaven National Laboratory, researchers observed that under specific conditions, one laser beam can block ...

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 ...

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

Researchers used a ruby crystal and specific laser wavelengths to demonstrate that a laser beam could obstruct light and ...
