This Is The World's Highest Peak-Power Laser Diode Array

Researchers at the Lawrence Livermore National Laboratory have created the world’s highest peak-power laser diode array, capable of creating up to 3.2 megawatts. The new device will be used in Europe’s new Extreme Light facility, which will be as badass as it sounds.


What Lockheed's New Laser Can Do

Briefly: Lockheed Martin recently tested its new Advanced Test High Energy Asset (ATHENA) laser — not to be confused with the Navy’s laser — on the Ford F-150 pictured above. The weapons system hit the truck’s running engine from a mile away. The engine doesn’t run any more.


IMAX's New Laser Projectors Make Me Wish I Lived In A Movie Theatre

Surround sound and 4K TVs are great for watching movies at home, but there’s still nothing like sitting in front of a gigantic screen in an IMAX theatre. I recently got an exclusive first look at the company’s next-generation digital laser projectors, and I walked away from the experience wanting to see every single movie remastered and projected using the new technology.


Reagan's Star Wars Missile Program Had Its Own Video Game

Remember US President Ronald Reagan’s plan for space weapons in the 1980s? Today, it’s little more than a punchline, but it used to be serious business. How serious? Video game serious. Yes, there really was an SDI video game, and thanks to the Internet Archive you can even play it.


This Laser Is Guided By Water

Sometimes, less is more — as in this turbine, which is having segments cut out with a laser for better cooling.


A Car Bumper Laser Helps Prevent Rear-End Collisions In Fog

It’s one of the most passive forms of weather on the planet, but fog accounts for countless pileups and accidents on roads and highways because drivers simply can’t see the cars in front of them. But this simple bumper-mounted laser promises to help remedy that by shining a bright red line on the road, 5m behind your vehicle, giving other drivers advance warning that you’re ahead of them.


Inventor Of The Laser Dies

Charles Townes, the physicist whose work would help lay the foundations for the development of the laser died today. He was 99. His career also ranged far beyond an interest in lasers, into astronomy and a fascination with spirituality.


Watch This Reflected Laser Pulse's Entire Flight Path At 20 Billion FPS

The technology available to image light as it moves through space continues to advance. Recently, we saw a new high-speed camera capture a small pulse reflected from a mirror; now, it’s possible to image the entire flight path of a laser as it bounces around a laboratory.


This Telescope Is Shooting A Laser Right At The ISS

Who gave this telescope a lightsaber? Just kidding. This is, of course, the ESA’s Optical Ground Station telescope in Tenerife — in the process of laser tagging the ISS to establish a data connection.


Ray Gun Rulers Make You Actually Want To Solve For Y

At some point in a child’s life they eventually make the connection that a long plastic ruler is not unlike the barrel of a gun, and suddenly maths homework gets a lot more enjoyable as they blast away at imaginary aliens between problems. The folks at Atypyk have taken that idea one step further with a pair of plastic toy ray guns that double as rulers and protractors.
