    Lasers could heat materials to temperatures hotter than the centre of the Sun in only 20 quadrillionths of a second, according to new research. Theoretical physicists from Imperial College London have devised an extremely rapid heating mechanism that they believe could heat certain materials to ten million degrees in much less than a million millionth of a second. The method, proposed here for the first time, could be relevant to new avenues of research in thermonuclear fusion energy, where scientists are seeking to replicate the Sun’s ability to produce clean energy. The heating would be about 100 times faster than...

    From hand-held blasters to planet-destroying death rays, laser weapons are a fanciful staple of science fiction. But at their core, lasers are just concentrated beams of light that generate heat. As simple as that sounds, they've proven remarkably difficult to weaponize. Until now. Quietly and without great fanfare the laser weapon has arrived, and warfare will never be the same. This week Lockheed Martin, the defense contractor behind the F-35 Joint Strike Fighter, announced it was exploring ways to put a laser on the controversial fighter. The U.S. Navy has already fielded a laser weapon on the USS Ponce. And...

    Experiments suggest that the carbon sheets can produce beams in broad range of colours. Graphene, hailed as one of the thinnest, strongest and most conductive materials ever found, seems to have bagged one more amazing property. Experiments suggest that it can be used to create ultrashort laser pulses of any colour, owing to an ability to absorb light over a broad range of wavelengths. The discovery could help researchers to build small, cheap and highly versatile ultrashort-pulse lasers, with potential applications ranging from micro-machinery to medicine. Conventional ultrashort-pulse lasers use a material that absorbs light like a sponge and then...

    Functional laser weapons are just five years away. Advocates hope that won’t always be the case. The Air Force has been working on airborne laser weapons for more than 40 years, but a fielded system remains elusive. Experts also warn that the US does not enjoy a commanding lead in laser research. And the Air Force’s flagship laser weapon program, the Airborne Laser (later called the Airborne Laser Testbed) was terminated late last year and is now being dismantled.

    British researchers say they've developed a laser process that can "uncopy" toner ink from paper as an alternative to traditional recycling. Scientists at the University of Cambridge say the process involves short laser pulses to erase words and images by heating the printed material to the point that it vaporizes. The technique works with commonly used papers and toner inks and is more eco-friendly than recycling, they said. "When you fire the laser, it hits the thin toner layer and heats it up until the point that you vaporize it," researcher David Leal-Ayala told the BBC. "Toner is mostly composed...

    Dr. Chunlei Guo and his team of Air Force Research Laboratory-funded researchers from the University of Rochester are using laser light technology that will help the military create new forms of metal that may guide, attract, and repel liquids and cool small electronic devices. The researchers discovered a way to transform a shiny piece of metal into one that is pitch black, not by paint, but by using incredibly intense bursts of laser light. Dr. Guo and his team have been working on creating technology that may enable the Air Force to create an additional kind of metal. The black...

    EADS Astrium engineers are working on an orbital solar power concept that they think will be competitive with other technologies but safer to use. Solar power would be collected in space and beamed to Earth using high-power infrared lasers so the energy could be used in remote regions, areas hit by natural disasters and other places where terrestrial power is not readily available. Astrium Chief Technical Officer Robert Laine says the concept offers certain advantages compared to competing technologies such as microwaves—notably a much smaller health risk. The idea of using IR lasers for energy transmission has been around for...

    The U.S. media suspects China and India of developing anti-satellite weapons. An article to this effect has been published the New Scientist magazine. Until recently, only the Soviet Union, its legal successor Russia and the United States were capable of developing anti-satellite weapons. U.S. analysts now think that China and India are acquiring similar capabilities. To what extent are such fears justified? It is hard to overestimate the role played by military satellite systems. Since the 1970s, an increasingly greater number of troop-control, telecommunications, target-acquisition, navigation and other processes depend on spacecraft which are therefore becoming more important. At this...

    India has begun development of lasers and an exoatmospheric kill vehicle that could be combined to produce a weapon to destroy enemy satellites in orbit, the director-general of India’s defense research organization said Jan. 3. “The kill vehicle, which is needed for intercepting the satellite, needs to be developed, and that work is going on as part of the ballistic missile defense program,” said V.K. Saraswat, director-general of the Defence Research and Development Organisation, which is part of India’s Ministry of Defence. In a televised press briefing during the 97th Indian Science Congress in Thiruvananthapuram, Saraswat said the program includes...

    KAISERSLAUTERN, Germany — The military is inching closer to using laser weapons on the battlefield after recent tests in which lasers were used to shoot down a drone aircraft and were fired from an airplane to damage a vehicle on the ground. The Air Force recently test-fired its Advanced Tactical Laser from a C-130 Hercules, scorching a truck’s hood. And last month the Army and Air Force teamed with Boeing Co. for a demonstration in which lasers on the ground shot down drones at China Lake, Calif., company officials said. Laser weapon projects in the works include the Navy’s powerful...
  • New Bomber To Focus Heavily On ISR

    The U.S. Air Force’s ISR chief says a new bomber design will be more about intelligence gathering and non-kinetic weapons than about bombing. The arsenal of this “long-range, ISR/Strike” aircraft may eventually include directed energy and network attack, says Lt. Gen. Dave Deptula, deputy chief of staff for intelligence, surveillance and reconnaissance (ISR). Directed energy weapons under development by the Pentagon include a range of lasers and devices that produce pulses of high-power microwaves. Other non-kinetic capabilities include the attack of enemy sensors with very precise, exotic-waveform jamming and the low-power, electronic invasion of networks that link tactical weapon systems...

    It sounds like something from a James Bond movie: a massive satellite, the largest ever launched, equipped with a powerful laser to take out the American anti-missile shield in advance of a Soviet first strike. It was real, though—or at least the plan was. In fact, when Soviet President Mikhail Gorbachev walked out of the October 1986 summit in Reykjavik, Iceland, because President Ronald Reagan wouldn't abandon his Strategic Defense Initiative, or SDI, the Soviets were closer to fielding a space-based weapon than the United States was. Less than a year later, as the world continued to criticize Reagan for...

    Boeing has announced the successful completion of two key reviews for the U.S. Army's High Energy Laser Technology Demonstrator (HEL TD) program. Completion of a critical design review in July allows Boeing to begin building a rugged beam control system on a Heavy Expanded Mobility Tactical Truck (HEMTT), a widely used military tactical vehicle. A system functional review in June addressed key enablers for fielding a next-generation, solid-state laser weapon system. "This demonstration program is making significant progress in developing a weapon system that will transform the way soldiers are protected on the battlefield," said Gary Fitzmire, vice president and...

    Enlarge ImageBoom! After being hit with laser beams, a small plastic pellet (sunlike object) emits x-rays, some of which bombard a pellet of silicon (blue and purple). Credit: Adapted from S. Fujioka et al., Nature Physics, Advance Online Publication A team of researchers has created conditions analogous to those found outside of a black hole by blasting a plastic pellet with high-energy laser beams. The advance should sharpen insights into the behavior of matter and energy in extreme conditions. Astronomers can't observe black holes directly because their immense gravity won't let light escape. Instead, they have focused on what...

    EDWARDS AFB, CA - The Boeing Company and the US Missile Defense Agency successfully completed the Airborne Laser's (ABL) first in-flight test against an instrumented target missile, achieving a historic milestone.During the test, the modified Boeing 747-400F used its infrared sensors to find a target missile launched from San Nicolas Island, Calif. The battle management system aboard ABL issued engagement and target location instructions to the beam control/fire control system, which acquired the target and fired its two solid-state illuminator lasers to track the target and measure atmospheric conditions.ABL then fired a surrogate high-energy laser at the target, simulating a...

    New approach offers more pleasant light of traditional bulbs without the energy guilt Thanks to a bit of ingenuity, Chunlei Guo, associate professor of optics at the University of Rochester, and his assistant Anatoliy Vorobyev have been able to squeeze out fluorescent-like energy performance from an incandescent light bulb. The breakthrough boils down to a laser treatment of the bulb's tungsten filament, a processing step which could one day become a standard in the light bulb industry. Traditionally, incandescent light bulbs provide more pleasant light, however they lack the efficiency of fluorescent designs. The new bulb offers the brightness and...
