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

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

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

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

The ability of new blue-light semiconductor lasers to better perform precision cutting, patterning or welding of copper will make electrical and electronic component manufacturing cheaper and more ...

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

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

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

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

A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

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

The interaction between the two light sources created a shadow on a screen that was visible as a dark area where the green laser blocked the blue light.
