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

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 ...

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 ...

Researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings could have huge implications for optical ...

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… ...

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 ...

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 2016, SLD Laser introduced its LaserLight surface mount device (SMD) that uses blue semiconductor lasers, phosphors, and high-luminance packaging to deliver about 500 lumens of white light from a ...
