Ti:Sapphire Laser Drives Accelerator on Chip
STANFORD, Calif., Oct. 1, 2013 — An advance that uses commercial lasers and low-cost, mass-production techniques could set the stage for a new generation of "tabletop" particle accelerators that are less expensive for use in science and medicine. Current state-of-the-art accelerators use microwaves to boost the energy of electrons. Researchers have sought more economical alternatives, and this new technique, which uses ultrafast lasers to drive the accelerator, is a leading candidate. A team that included scientists f...

Light stopped for a minute
DARMSTADT, Germany – At 186,000 miles per second, the speed of light is unparalleled, so slowing it down is a formidable challenge – and stopping it seems impossible. But physicists in Germany report using a glasslike crystal to stop light for about one minute,...
Control could make random lasers useful
VIENNA – Random lasers, with their very irregular angular emission pattern, are difficult to tune. But a team at Vienna University of Technology has theoretically shown that random lasers can be controlled by actively shaping the spatial pump distribution,...
On-chip squeezed light could improve sensors
PASADENA, Calif. – A microchip-based way to create squeezed light could assist a range of precision measurements and provide a viable route toward real-world on-chip sensor applications and technology. Monitoring a mechanical object’s motion, even with a touch...
Superman crystal ‘can secure the last evidence of civilization’
SOUTHAMPTON, England – Nanostructured glass could be the key to storing vast quantities of information on a single disc for more than a million years. A new technology uses a femtosecond laser to record digital text in 5-D via self-assembled nanostructures created in...
‘Embedded eigenvalue’ holds promise for sensors, lasers, more
CAMBRIDGE, Mass. – There are several ways to confine light, but a new approach uses two waves of the same length, but exactly opposite phases, to cancel each other out, allowing light of other wavelengths to pass freely. In mathematical terms, the new phenomenon...
Photodetector discerns polarized light intrinsically
HOUSTON, and LIVERMORE, Calif. – Few photodetector materials can discern polarized light directly without a grate or a filter, but a newly created carbon-based broadband photodetector demonstrates intrinsic polarimetry. A team from Rice University and Sandia National Laboratories...
