Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth ...
A new study published in Nature Physics describes how a team of scientists used a laser beam to gain access to long-lived soundwaves in crystalline solids as the basis for a potentially new approach to information processing ...
A collaboration of scientists from five of the world's most advanced x-ray sources in Europe, Japan and the US, has succeeded in verifying a basic prediction of the quantum-mechanical behavior of resonant systems. In the ...
A "chemical imaging" system that uses a special type of laser beam to penetrate deep into tissue might lead to technologies that eliminate the need to draw blood for analyses including drug testing and early detection of ...
Lockheed Martin has completed the design, development and demonstration of a 60 kW-class beam combined fiber laser for the U.S. Army.
Physicists want to use ultracold gases in space to measure the Earth's gravitational field, to subject Einstein's Equivalence Principle to an accurate test, and also to detect gravitational waves. The first flight in a sounding ...
The European X-ray Free-Electron Laser (XFEL) facility, near Hamburg, Germany, was built with one objective—to provide pulses of light short enough, bright enough, and of small enough wavelength to observe processes that ...
A largely unrecognized field called photonics may provide solutions to some of NASA's most pressing challenges in future spaceflight.
After years of work, a team of NASA scientists and engineers is poised to realize a lifetime goal: building an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements ...
A team of scientists at Lomonosov Moscow State University and the Belarusian National Technical University has created a unique laser. It's a compact light source with wavelengths harmless to the human eye. The device can ...
