World's Newest, Most Powerful Laser Comes Online

deglr6328 writes "The OMEGA EP laser at the University of Rochester's Laboratory for Laser Energetics was dedicated today at the Robert L. Sproull Center for Ultra High Intensity Laser Research. The new laser, which has been in design since ~2002 will, at 1 kilojoule per 1 picosecond pulse, be the highest energy petawatt scale laser ever created by far. For a fleeting fraction of a second, it will deliver a beam of infrared light at 1054 nm that is more powerful than the total energy consumption of all human activity on the planet, to a tiny spot the size of the head of a pin. Previous petawatt scale lasers such as the one created at Lawrence Livermore labs in the late 90's (and dismantled in 1999) were capable of only several hundred joules per pulse.

Breakthrough In Plastic Lasers

esocid writes "Conventional electrically-powered laser diodes used in everyday consumer goods like DVD players are currently based on inorganic semiconductor materials such as gallium arsenide, gallium nitride, and related alloys. Plastic laser diodes offer the promise of covering more of the light spectrum than their counterparts, from near ultraviolet to the near infrared. Yet despite over a decade of research worldwide, plastic laser diodes have not yet been demonstrated because there haven't been any plastics that could sustain a large enough current while also supporting the efficient light emission needed to produce a laser beam. Now researchers at Imperial College London, publishing their findings in Nature Materials in April, are studying a plastic related to PFO (polydioctylfluorene), a blue-light emitting material; by making sub

Laser Could Help Find Earthlike Planets

Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. The same NIST group also has shown that this type of laser, when used as a frequency comb—an ultraprecise technique for measuring different colors of light—could boost the sensitivity of astronomical tools searching for other Earthlike planets as much as 100 fold.

Record-Setting Laser May Boost Search For Earthlike Planets 100 Fold

Can Light be "Squeezed" to Improve Sensitivity of Gravitational Wave Detectors?

The search is on to detect the first evidence of gravitational waves travelling around the cosmos. How can we do this? The Laser Interferometer Gravitational-Wave Observatory (LIGO) uses a system of laser beams fired over a distance of 4 km (2.5 miles) and reflected back and forth by a system of mirrors. Should a gravitational wave pass through the volume of space-time surrounding the Earth, in theory the laser beam will detect a small change as the passing wave slightly alters the distance between mirrors. It is worth noting that this slight change will be small; so small in fact that LIGO has been designed to detect a distance fluctuation of less than one-thousandth of the width of a proton. This is impressive, but it could be better. Now scientists think they have found a way of increasing the sensitivity of LIGO; use the strange quant

Laser heats up the fusion future

The world's most powerful laser has heated matter to 10 million Celsius, hotter than the surface of the Sun.

Laser fast-tracks nanomaterial production

Zapping a mixture of iron powder and methanol with a laser can produce useful quantities of iron oxide nanostructures in a matter of minutes. Developed by researchers at the University of Surrey, UK, the process can deliver nanobelt- or nanowire-shaped material depending on the methonal flow rate.

Saitek Cyborg Laser Gaming Mouse Review

The Cyborg Laser Mouse is a part of many other gaming peripherals on the Cyborg series put out by Saitek. This mouse offers a unique design with many features. These include pre-installed Hyperglide mouse feet, 10 programmable buttons, 3200DPI, and a motorized mouse extension. I've seen mice with adjustable weights and adjustable buttons before, but this is the first time that I have seen a mouse with an adjustable length. Read on further to see the mouse in action.�

Physicists Develop Laser With Bandwith Spanning Two Telecom Windows

A team of physicists in the Institute for Ultrafast Spectroscopy and Lasers (IUSL) of the Physics Department at The City College of New York (CCNY) have developed new near-infrared broadband laser materials with tunability ranges around triple those of earlier crystals. The new crystals have a tunability range of as much as 460 nanometers (nm) and have potential application in such fields as telecommunications, biomedical imaging and remote sensing.
