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 ...

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 ...

Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

Final tests of NASA's laser beam communication technology suggests we'll soon have a new way to keep in touch with astronauts and spacecraft venturing into deep space. Final tests of NASA's laser beam ...

The first operational high-power laser beam will be deployed this year, providing a cost-effective and rapid solution for ...

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 ...

JERUSALEM, Sept 17 (Reuters) - A low-cost, high-power laser-based system aimed at destroying incoming missiles has successfully completed testing and will be ready for operational use by the military ...

A tiny, levitated bead is at the core of an unprecedentedly bright laser that shoots particles of sound instead of light. Just as a ray of light is made up of many particles called photons, sound ...
