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 ...

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 ...

Earlier this summer, Israel made military history. Not with a missile, bomb or bullet — but with a beam of light. In a first for modern warfare, the Israel Defense Forces successfully intercepted ...

The laser-defense system called the "Iron Beam" was first unveiled in 2014. (AP) Loreben Tuquero October 19, 2023 Video footage of beams of light pulsing through the night sky prompted speculation ...

NASA announced on Wednesday that the agency successfully received data in the farthest-ever demonstration of laser, or optical, communications. Scientists say that NASA’s Deep Space Optical ...

Rafael has successfully tested its Iron Beam laser weapon in various scenarios against steep-track threats, including UAVs, mortars, rockets, and anti-tank missiles. The weapon is set to complement ...

The Iron Beam is the most advanced, operational laser in the world, though England, the US, and others have relatively advanced lasers. In a historic breakthrough, the IDF on Wednesday announced that ...

A new paper recently revealed that an artificial intelligence-driven laser that can identify and zap cockroaches has been developed. "In this study, we present a laser system automated by machine ...

New research uses infrared light to transmit wireless power to devices nearly 100 feet away. The new laser charging system is aimed at offering safe, cordless power for mobile devices and sensors.

Laser linewidth measures how precisely a beam of light maintains its frequency and color purity. The narrower the linewidth, the more monochromatic and spectrally pure the laser. The team's ...

A NASA laser just fired successfully in a deep-space test. On Nov. 14, NASA picked up a laser signal fired from an instrument that launched with the Psyche spacecraft, which is currently more than 10 ...
