Atto, boy! Eggheads fire laser for 43 attoseconds, fastest Man-made spurt

Physicists have whittled down the world’s shortest laser pulse to just 43 attoseconds (4.3 x 10-17 seconds), fast enough to observe electrons moving during chemical reactions in slow motion for the first time. The blip “is the shortest controlled event that has ever been created by humans,” the boffins bragged. The …

Argentina eyes up laser death cannon testbed warship

Argentina reportedly wants to buy the US Navy’s laser death ray testbed warship, the fearsomely named USS Ponce. According to the Mail on Sunday, the Argentinians are interested in buying the 46-year-old former landing platform (dock) from the American Navy when she is decommissioned next year. “Senior Pentagon sources have …

Florida man is world's fastest flasher: Just 53 quintillionths of a sec

Physicists at the University of Central Florida have developed the world's fastest X‑ray pulse, at 53 attoseconds. Blink and you'll really, really miss it. At 53 quintillionths (53 x 10‑18) of a second, the flash is 15 orders of magnitude faster than the blink of an eye. The beam travels less than one-thousandth of the …

Boffins with frickin' laser beams chase universe's mysterious trihydrogen

Scientists are getting closer to piecing together the chemical reactions that form trihydrogen, one of the most abundant yet mysterious ions floating around in space. Trihydrogen, H3+, is an important molecule. It is believed that the tiny ion kickstarted a whole chain of reactions that led to the birth of the first stars in …

Talk about cutting-edge technology! Boffins fire world's sharpest laser

A team of physicists claims to have created the world's sharpest laser, with a line width frequency of only 10 millihertz – opening up the possibility of improving the accuracy of optical clocks and radioastronomy experiments. Lasers are, ideally, a concentrated stream of photons at a single frequency. But in reality the light …

US military's latest toy set: Record-breaking laser death star, er, truck

Vid Lockheed Martin says it is ready to deliver its most powerful laser weapon yet to the US military. This Death-Star-on-wheels can shoot down drones, missiles, and similar stuff, we're told. The American weapons conglomerate self-funded the building of a 30kW test system and then scaled the design up. The 60kW version is mounted …

Boffins build laser satellite data link

A satellite's radio-communications failing is a crisis if you need to keep it from drifting off station, so a pair of boffins suggest firing up an Earth-bound laser as a backup comms channel. The idea comes from Xinchen Guo of Purdue University and Jekan Thangavelautham of Arizona State University, in a paper they've prepared …

Laser beam sky mirage cannon can spy on enemies and generate Star Trek-style shields

British defence contractor BAE Systems says it has developed a laser-powered "mirage on demand" which can be used to bend the very fabric of the skies to military commanders' whims. The Laser Developed Atmospheric Lens, developed at BAE's Warton factory in Lancashire, works by "changing the Earth's atmosphere into lens-like …

Forget aircraft – now cretins are laser-blinding ferry boat crewmen

The Washington State Ferry service, on the US west coast, appears to have some high-tech enemies: a series of laser attacks have been fired at pilots on the craft that serve Seattle's Elliott Bay and the surrounding locales. On New Year's Eve the captain and the first mate of the ferry Tacoma were temporarily unsighted when …

British military laser death ray cannon contract still awarded, MoD confirms

The Ministry of Defence has today re-announced for the third time that it has awarded a £30m contract to build a great big feck-off laser cannon for zapping the Queen's enemies. Originally awarded in July 2016 to the Dragonfire consortium, the Laser Directed Energy Weapons (LDEW) contract immediately stalled after a challenge …

MoD confirms award of giant frikkin' laser cannon contract

The Ministry of Defence confirmed today that it is spending £30m on a laser cannon proof-of-concept demonstrator, following a challenge to the award of the contract some months ago. The £30m deal for the Laser Directed Energy Weapon (LDEW) demonstrator will go to a consortium led by part-French defence firm MBDA, as reported …

MIT's chip fires frikkin' laser at qubits

MIT boffins reckon they've cracked one of the more difficult challenges of practical quantum computing – the miniaturisation of components. In a paper at Nature, the Karan Mehta, Colin Bruzewicz, Robert McConnell, Rajeev Ram, Jeremy Sage and John Chiaverini say they've printed an ion trap and optical waveguide together in a …

F-35 targeting system laser will be 'almost impossible' to use in UK

US restrictions on the F-35 fighter jet's targeting system will make it “almost impossible” for training to be carried out in the UK, the Ministry of Defence fears – but its press office insists the constraints are normal. The F-35's electro-optical targeting system (EOTS) includes a target designator laser and a laser …

Missile bods MBDA win Brit military laser cannon contract

A consortium led by European missile company MBDA has reportedly won the contract to build a laser cannon for the Ministry of Defence, according to unconfirmed reports. The project, awarded under the Laser Directed Energy Weapon (LDEW) demonstrator project announced last year, is for a prototype to demonstrate whether firing a …

Laser-zapping scientists will save the Earth from meteorite destruction

Californian scientists are testing a system this month that may save humanity in the not-too-distant future. Boffins at the Lawrence Livermore National Laboratory (LLNL) will fire up high-energy lasers to see if they can successfully vaporize rocks from outer space. But don't worry; your tax dollars aren't being used to build …

Boffins build laser that can twist its own light

The world has known that information can be encoded on “twisted light” for some time, but only with complex equipment. Now, boffins from South Africa have demonstrated a laser that can add the twist at its output. The Register will resist the temptation to call this some kind of game-changer, but it's a useful development, …

NASA boffin wants FRIKKIN LASERS to propel lightsails

If you're familiar with the Larry Niven / Jerry Pournelle novel The Mote in God's Eye, get ready for a dose of Déjà vu: a NASA scientist has posted a video on the agency's NASA 360 YouTube channel describing how lasers could send a spacecraft from Earth to Mars in three days. He's perfectly serious, it seems: instead of having …
