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 ...

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

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

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