Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

We’re all used to receiving data wirelessly, but transmitting power over the air has been much trickier. Now Korean engineers have demonstrated a new system that uses infrared lasers to beam power as ...

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...

Since the discovery of lasers, laser outputs have been limited to simple wavefront profiles, such as Gaussian (with the highest intensity in the middle, and lower intensity towards the tails) and ...

In a move that sounds like the wildest of science fiction, DARPA has announced its new Persistent Optical Wireless Energy Relay (POWER) program that plans to use lasers relayed by airborne platforms ...

Physicists at the SLAC National Accelerator Laboratory just created a petawatt laser beam with the highest peak power and current ever. This beam was formed from a bunch of electrons that were ...

For the first time, scientists were able to show they can bend lightning from a storm with a laser. The project, 20 years in the making, required a super powerful laser to be shot into the sky. The ...

Officials from CommonSpirit St. Elizabeth Hospital and Flight For Life are looking into an incident involving a blue laser and the Lifeguard 6 helicopter on July 10. According to the officials, a ...

Israel expects its “Iron Beam” laser defense system to be operational within one year, saying it will bring “a new era of warfare” as it engages in a war of drones and missiles with Iran and its ...

TALLAHASSEE, FLA. (WSVN) - A teen has been arrested after, police say, he repeatedly aimed a laser beam at a helicopter crew. Helicopter cameras captured a green laser on the ground in Tallahassee ...
