For a while missiles looked like potential prey. They have thin skins and are packed with fuel and explosives. Merely damaging the shell of a supersonic missile can create drag, causing it to tumble ...

Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

Israel has developed three laser air defence systems that can track and destroy enemy fighter jets, drones, and missiles ...

Israel’s enemies have known that 85%-95% of their short-range rockets would be shot down by Iron Dome. But they also knew ...

Laser beams with a 'twist': New spiral laser for twisted light Date: March 15, 2016 Source: University of the Witwatersrand Summary: Using geometric phase inside lasers for the first time ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the ...

The light-shadow experiment began when physicists led by Raphael Akel Abrahao sent a high-power beam of green laser light through a cube-shaped ruby crystal. They then illuminated this beam from the ...

AIR AND SPACE NASA receives laser beam from 10 million miles away: 'First light' An agency spacecraft sent test data back to the Hale Telescope at Caltech’s Palomar Observatory in California ...

In 2011, researchers in China calculated that a type of laser called a Bessel beam, which puts out light in concentric rings, could be designed to make a particle inside the beam emit photons on ...

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&#82… ...
