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… ...

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

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 ...

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 ...

A laser produces one beam, and that beam is usually limited to one or two users at a time. ... The electrons travel in a bunch, which has to be very short to ensure that you get laser light.

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 ...
