  • All fired up over world's biggest X-ray laser gun

    08/31/2017 6:05:59 PM PDT · by BenLurkin · 24 replies
    A sleek, subterranean X-ray laser set to be unveiled in Germany today, the most powerful in the world yet, has scientists in a dozen fields jostling to train its mighty beam on their projects. European XFEL will reveal - and capture in images - secrets at the sub-atomic level, promising breakthroughs in medicine, biology, energy, information technology and chemistry. It will map the molecular architecture of viruses and cells, render three-dimensional nano-scale snapshots and film chemical reactions as they unfold. Earth scientists should be able to duplicate and study processes occurring deep inside planets, including our own. "The laser is...

    The laser, known as the Laser Weapons System (LaWS), may seem as though it were pulled straight from a James Bond movie, but it's entirely functional and can shoot with stunning accuracy, the U.S. Navy told CNN. The LaWS is currently deployed aboard the USS Ponce, an amphibious transport ship, in the Persian Gulf. "Operationally, it works just like a laser pointer," Lt. Cale Hughes, a LaWS officer, told CNN. "There's a chamber inside with special materials that release photons." ... The $40 million system requires a team of three to operate it and a small generator to power its...

    On Monday, Raytheon, a high energy laser system developer for the US army, said that it had bolted a laser to a U.S. Army Apache AH-64 helicopter and zapped an unmanned target at the White Sands Missile Range in New Mexico. The weapons test marked the first time a “fully integrated laser system” had successfully located and shot a target from a rotary-wing aircraft “over a wide variety of flight regimes, altitudes and air speeds,” the company said in a statement. Raytheon didn’t specify what the target was but said the helicopter’s laser “directed energy” on it from nearly a...

    Beam-Riding and Sail Stability by Paul Gilster on June 23, 2017 Breakthrough Starshot, the ambitious 30-year plan for launching small interstellar craft to a nearby star, depends critically on the sails that will ride a laser beam to 20 percent of lightspeed. In the essay below, James Benford takes a hard look at where we are now in the matter of sail stability, a subject he and brother Gregory have analyzed in their laboratory work. But as Jim points out, there is a great deal we still don’t know, emphasizing the need for a dedicated test facility in which deep...

    MDA seeks laser-armed HALE UAV for counter-ICBM role Gareth Jennings 14 June 2017 The United States is looking to field a laser-armed unmanned aircraft to intercept intercontinental ballistic missiles (ICBMs) towards the middle of the next decade, the Missile Defense Agency (MDA) disclosed on 13 June. In a solicitation posted on the Federal Business Opportunities (FedBizOpps) website, the MDA Advanced Technology Directorate said it requires a high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV) with the payload capacity needed to carry a high-energy laser system payload to high altitudes for Boost Phase Intercept (BPI) of ICBMs in the 2023 timeframe. "The...

    Devious humans have given green lasers a bad name. Aiming a laser at an aircraft or the flight path of an aircraft is illegal according to a 2012 U.S. federal law. Jail time awaits offenders. Don’t point at a police officer either.... But if you mind your manners, a green laser is one of the best tools available to amateur astronomers eager to share the wonders of the night sky with the public. There’s simply nothing better to point out constellations, comets, individual stars and satellites in the night sky. Amateurs love ’em! So does the public. Go to a...

    A WestJet pilot sought medical attention after a laser strike during a flight to Fort McMurray last month, airline officials say. The laser was shone into the cockpit of a WestJet aircraft on Aug. 22, WestJet spokeswoman Lauren Stewart said in an email. The flight landed safely in Fort McMurray, but the next flight was cancelled until a replacement co-pilot could be brought in. Pilots are trained to look away to protect their eyes in the event of a laser strike, but the pilot was advised to seek medical attention as a precaution. "A laser has the potential to cause...

    Stephen Hawking is backing a project to send tiny spacecraft to another star system within a generation. They would travel trillions of miles; far further than any previous craft. A $100m (£70m) research programme to develop the computer chip-sized "starships" was launched by the billionaire Yuri Milner, supported by Facebook founder Mark Zuckerberg. Interstellar travel has long been a dream for many, but significant technological hurdles remain. But Prof Hawking told BBC News that fantasy could be realised sooner than we might think.

    'Laser Cloak' Could Hide Earth from Evil Aliens A new paper describes how laser beams could disrupt measurements of Earth's orbit around the sun, potentially deceiving inquisitive aliens. Here, a 22W laser used for adaptive optics shines from the Very Large Telescope in Chile. Credit: ESO/G. Hüdepohl A simple laser beam could disrupt aliens' observations of Earth, making it look like there's nobody home on the third rock from the sun, a new study suggests. David Kipping, an astronomer at Columbia University in New York, said he first considered this idea when he heard about the strangely dimming star that...

    Figure 9 from “A Roadmap to Interstellar Flight”Guest essay by Eric WorrallAn American scientist has made a remarkable conceptual breakthrough, a design for a non nuclear relativistic launcher, capable of accelerating thousands of deep space probes per year to 0.25C; fast enough to reach the nearest stars in 15 years. The system is extremely scalable – you could start with a small, low cost proof of concept launcher, and work up to bigger devices, capable of launching substantial probes into interstellar space. The system also has a practical alternative use – the full size version is powerful enough to deflect...

    The Pentagon kills language. Housing the brain and central coordinating organs of the most advanced military the world has ever known, the Depart of Defense headquarters can take an announcement as exciting as "the U.S. Army is working on laser guns" and distill it to, in the words of Mary J. Miller, deputy assistant secretary of the Army for Research and Technology, "aligned to transition into a program of record in the fiscal 2023 timeframe." Make no mistake: bland phrasing aside, the Army is going to fund laser weapon development in the next decade. The remarks came last week as...

    The US Army is planning to deploy the first laser weapons in 2023, it has been revealed. Mary J. Miller, deputy assistant secretary of the Army for Research and Technology, told the House Armed Services Committee's Subcommittee on Emerging Threats and Capabilities 'I believe we're very close,' when asked how close the Army is to developing offensive and defensive directed-energy weapons. She said the programmes would be extensively tested as the Army wants to understand the lasers' full capabilities 'before we offer it to a Soldier.' 'It's being done in a 'step-wise demonstration of capability,' she said. 'We have to...

    Laser cutters use lasers to cut shapes into existing material, but Rice University scientists have figured out how to make one build objects instead of cut them. The result is the $2,000 3D printer that you see above, constructing the blood vessel network inside a mouse liver. If we want to maximize the usefulness of 3D printers, we have to maximize the number of materials they can work with, while minimizing the cost. That was the goal of the Rice scientists, when they devised a way to make a 3D printer with a couple of days, a couple of thousand...

    It sounds like science fiction, but it's eminently possible, researchers say: Robotic spacecraft could get to Mars after a journey of just three days. The key to making this happen is photon propulsion, which would use a powerful laser to accelerate spacecraft to relativistic speeds, said Philip Lubin, a physics professor at the University of California, Santa Barbara. "There are recent advances which take this from science fiction to science reality," Lubin said at the 2015 NASA Innovative Advanced Concepts (NIAC) fall symposium last October. "There's no known reason why we cannot do this." Lubin and his team were awarded...

    Pondering Gravitational Wavesby Paul Gilster on February 11, 2016 "Einstein would be beaming," said National Science Foundation director France Córdova as she began this morning's news conference announcing the discovery of gravitational waves. I can hardly disagree, because we have in this discovery yet another confirmation of the reality of General Relativity. Caltech's Kip Thorne, who discussed black hole mergers way back in 1994 in his book Black Holes and Time Warps, said at the same news conference that Einstein must have been frustrated by the lack of available technologies to detect the gravitational waves his theory predicted, a lack...

    The invention of guns took warfare to a whole new level. Later, airplanes radically changed it again. Now, experts say another big shift is coming, led by energy weapons, including lasers. The U.S. Air Force Research Laboratory, or AFRL, said it's on track to demonstrate a working laser weapon on a fighter jet by 2020. "It really is a national tipping point," said Kelly Hammett, chief engineer for the AFRL's directed energy directorate. "We see the technology evolving and maturing to the stage where it really can be used." Arming larger planes with laser weapons has been possible for years....
