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

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

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 ...

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 ...

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 ...

There are lots of situations where getting a look at the human brain can be very helpful. Unfortunately, our heads are famously opaque, so decades of research and development have gone into finding ...

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.

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 ...
