Flashing a laser into the cockpit of an airplane can distract, even temporarily blind pilots. Minnesota incidents have ...

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

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

Brookhaven researchers have revealed that a laser beam can cast a shadow through nonlinear optical processes, challenging ...

Researchers create a visible shadow using only a laser beam, an achievement that seemingly defies conventional physics.

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

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

With the help of a ruby cube and two laser beams, researchers made one ray of light cast a shadow when illuminated by the ...

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

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

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

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening ...
