A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is ...

When a light beam of time-independent intensity hits a transparent object, the light does not get absorbed but is scattered by the material -- a phenomenon caused by the unitary property of the ...

Normally, the gas won't allow light to pass through it. But it can be made transparent by illuminating it with a laser beam, called the 'coupling beam'.

Here, we propose and experimentally demonstrate an approach to hide a high-resolution grayscale image in a square laser beam with a size of less than half a millimeter.

Light normally travels at about 299,000 kilometres per second (186,000 miles per second), but it slows down when passing through some materials, such as glass. The team fired a light beam called a ...

HP has become the first company to preview hardware built with Google Beam, the 3D video communication technology formerly known as Project Starline. It’s launching the HP Dimension, a device ...

Researchers discovered in 1992 that a beam of light could have orbital angular momentum, meaning that the beam twists as it propagates forward, with each photon circling around the centre of the beam.

The beam itself is powered by four purple lasers that sit atop the entrance of the Golden 1 Center, the Kings home arena. Because of its placement, the beam illuminates Sacramento's skyline when lit.

The Sacramento Kings look to break a record-long NBA playoff drought. Golden 1 Center’s new laser beam after wins is a symbol of hope.
