In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Scientists have beamed a laser into the sky, which was visible from miles around. The spectacle, known as The Beam, marked the 80th birthday of Harwell Science and Innovation Campus in Oxfordshire.

A pillar of light illuminated the sky in Oxfordshire as part of a birthday celebration for Harwell Science and Innovation Campus.

The US and China are racing to build space-based solar power infrastructure that would beam electricity down to Earth 24/7.

It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about the “pew-pew” factor that makes ...

A NASA spacecraft has beamed a near-infrared laser nearly 10 million miles into space breaking new ground for the agency. The laser, which is encoded with test data, was fired from NASA’s Psyche ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
