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 ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a surprisingly ...

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

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

The future of transmitting massive amounts of data digitally may be here, thanks to new technology that uses a "hurricane" of ...

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

The discovery, centred around controlling tiny hurricanes of light and electromagnetic fields, could revolutionise how much information we can deliver over cables.

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

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

To create the chip, researchers used an integrated optical phase array, which contains microscale antennae that are ...

Durability, whether you prefer flood, spot or adjustable beams, and the type of light -- LED, incandescent or krypton -- are other important factors to consider. CNET spent hours researching and ...
