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 ...
