Engineers and applied scientists from Harvard University have demonstrated a new photonic device with a wide range of potential commercial applications, including dramatically higher capacity for optical data storage.
Fourteen laser ranging stations participated in a campaign to track ESA's GIOVE-A satellite during the spring and summer of 2006, providing invaluable data for the characterisation of the satellite's on-board clock.
Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's.
The most powerful tunable laser in the world just shattered another power record: the Free-Electron Laser (FEL), supported by the Office of Naval Research and located at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), produced a 14.2 kilowatt (kW) beam of laser light at an infrared wavelength of 1.61 microns on October 30.
An artificial, laser-fed star now shines regularly over the sky of Paranal, home of ESO's Very Large Telescope, one of the world's most advanced large ground-based telescopes.
Cotton may be getting even more breathable. A new wave of fiber research debuts with an international science and technology conference.
We have to climb a mountain in order to conquer it. In quantum physics there is a different way - objects can reach the opposite side of a hill simply by tunnelling through it, instead of laboriously climbing over it.
A new type of diode laser, called the quantum cascade laser (QCL), may eventually change this situation. Diode lasers are inherently compact and suitable for mass-production, which has led to their widespread and low-cost use in everyday products, including CD and DVD players.
A compact, inexpensive method for stabilizing lasers that uses a new design to reduce sensitivity to vibration and gravity 100 times better than similar approaches has been demonstrated by scientists at JILA.
Just as clouds block the sun, they interfere with laser communications systems, but Penn State researchers are using a combination of computational methods to find the silver lining and punch through the clouds.
