(THE CONVERSATION) Nations around the world are rapidly developing high-energy laser weapons for military missions on land and sea, and in the air and space. Visions of swarms of small, inexpensive ...

There are many different types of lasers—almost as many as there are applications for the same—but what ties them all together as a class is that they depend on the same physical effect: stimulated ...

Add Yahoo as a preferred source to see more of our stories on Google. Green laser beam coming from a hand-held laser pointer. They're in grocery store scanners, internet connections and car backup ...

The mechanism that can cause a rapidly expanding plasma—the superhot state of matter harnessed in fusion energy systems—to spontaneously generate its own magnetic fields was identified through a new ...

A team of international researchers, including an Aston University researcher, has cracked the code on how "breather" laser pulses work, creating a single mathematical model that explains two ...

High-energy lasers are increasingly being viewed as a cost-effective way to defend against drones and missiles, especially those launched by Iran at oil refineries and US bases across the Middle East.

Using intense X-rays, researchers captured a buckyball as it expanded, split and shed electrons under strong laser fields. Detailed scattering measurements showed how the molecule behaves at low, ...

The Bomem DA3 is a type of Fourier transform spectrometer used for measuring various spectral data and [Usagi Electric] has one. On his quest to understand it he runs down a number of rabbit holes, ...

Who doesn't love a humongous laser? Here at ExtremeTech, we're fans of both 1) technology and 2) extremes, and lasers are toward the far end of both spectra. So, do you have a minute? In the spirit of ...
