    Toward a High-Velocity Astronomyby Paul Gilsteron May 15, 2019 Couple the beam from a 100 gigawatt laser with a single-layer lightsail and remarkable things can happen. As envisioned by scientists working with Breakthrough Starshot, a highly reflective sail made incredibly thin — perhaps formed out of graphene and no thicker than a single molecule — could attain speeds of 20 percent of c. That’s good enough to carry a gram-scale payload to the nearest stars, the Alpha Centauri triple system, with a cruise time of 20 years, for a flyby followed by an agonizingly slow but eventually complete data return....

    U.S. Air Force says a ground-based laser downed multiple test missiles over New Mexico. A successful ground test has moved the U.S. military one big step closer to putting anti-missile lasers on its aircraft. A ground-based laser shot down several missiles in flight during an April 23 test at the White Sands Missile Range in New Mexico, Air Force officials said. Run by the Air Force Research Laboratory, or AFRL, the test was part of the Self-Protect High Energy Laser Demonstrator, or SHiELD, a program intended to protect aircraft from incoming missiles. AFRL officials said security reasons prevented them from...

    DARPA was interested in creating a chip-scale laser optical gyroscope. Important for its ability to maintain knowledge of position without GPS, optical gyroscopes are used for precision positioning and navigation, including in most commercial airliners. The laser optical gyroscope has a length-scale sensitivity on par with that of the gravitational wave detector, one of the most precise measuring instruments ever made. But current systems that achieve this sensitivity incorporate bulky coils of optical fiber. The goal of the OwlG project was to realize an ultra-quiet (narrow-linewidth) laser on the chip to replace the fiber as the rotation-sensing element and allow...

    A KMBC 9 News photojournalist's camera caught someone using what appears to be a laser pointer directed at Tom Brady's face during Sunday nights AFC Championship game at Arrowhead Stadium. The first instance caught on camera was on a hand-off from Tom Brady to Sony Michel in the fourth quarter. The previous play was a punt that appeared to be muffed by Patriots' receiver Julian Edelman but was later overturned. Laser researcher Charles Cobb, DDS, MS, PhD., said based on the size of the spot, it looks like the person was sitting far back in the end zone, possibly in...

    The weapon is 'mainly expected to be for Chinese police use' ___________________________________________________________________ A Chinese firm has developed a laser gun designed for police use that can set fire to protesters' hair or banners from a range of almost one kilometre. The general manager of the ZKZM fiber laser company, who asked to remain anonymous, said the weapon would "immediately" produce a "strong pain response" in the target but stressed it was designed to be "non-lethal". "The weapon is designed to do things such as setting fire to illegal banners at a protest or setting fire to the hair or...

    A laser powerful enough to tear apart the fabric of space could be built in Britain. The major scientific project will follow in the footsteps of the Large Hadron Collider and will answer questions about the universe. The laser will be capable of producing a beam of light so intense that it will be similar to the light the earth receives from the sun but focused on a speck smaller than a pin prick. Scientists say it will be so powerful they will be able to boil the very fabric of space and create a vacuum. A vacuum fizzles with...

    The Chinese are building a laser that is 10 trillion times more intense than the sun and could rip apart space. Physicists say that this laser could be operational as early as 2023. Physicist Ruxin Li and colleagues are breaking records with the most powerful pulses of light the world has ever seen. At the heart of their laser, called the Shanghai Superintense Ultrafast Laser Facility (SULF), is a single cylinder of titanium-doped sapphire about the width of a Frisbee. After kindling the light in the crystal and shunting it through a system of lenses and mirrors, the SULF distills...

    THE US Navy will mount a laser weapon onto a top-class warship, defence officials confirmed. Top Navy officials said the device is slated to be installed on the USS Portland by this autumn. Crucially, the prototype will not be used in combat, but may pave the way for high-tech lasers that will be used during warfare. Captain Brian Metcalfe said: Theyve got what I call power modules that control the laser that will just fit in those open and reserve weight spaces and then the laser itself gets bolted onto the deck. Its not going to be integrated into the...

    A laser-driven technique for creating fusion that dispenses with the need for radioactive fuel elements and leaves no toxic radioactive waste is now within reach, say researchers. Dramatic advances in powerful, high-intensity lasers are making it viable for scientists to pursue what was once thought impossible: creating fusion energy based on hydrogen-boron reactions. And an Australian physicist is in the lead, armed with a patented design and working with international collaborators on the remaining scientific challenges. In a paper in the scientific journal Laser and Particle Beams today, lead author Heinrich Hora from the University of New South Wales in...
