The study was published the week of February 10–14 in the online edition of the Proceedings of the National Academy of Sciences. The work is the result of a five-year effort by researchers in the laboratory of Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and professor of electrical engineering; the project was led by postdoctoral scholar Christos Santis (PhD '13) and graduate student Scott Steger.
NASA's Curiosity Mars rover has passed the milestone of 100,000 shots fired by its laser. It uses the laser as one way to check which chemical elements are in rocks and soils.
Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy available from the more energetic photons in the visible part of the spectrum.
An advanced laser system offering vastly faster data speeds is now ready for linking with spacecraft beyond our planet following a series of crucial ground tests. Later this year, ESA’s observatory in Spain will use the laser to communicate with a NASA Moon orbiter.
A new laser capable of showing what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below.
A laser device originally designed to measure carbon on Mars could soon be used here on Earth to root out counterfeit foods, making sure that honey, olive oil and chocolate are what they claim.
A recently discovered patent application outlines an Apple-designed system that uses lasers and image sensors to facilitate a sense of depth perception.
The Pentagon has been developing both offensive and defensive laser weapon capabilities for a number of years.
US Navy ships may be fitted with laser weapons within just a few years.
Yesterday, an invader from another planet fired off a laser 30 times, in what we have to hope won't be seen as an act of aggression by any overlooked Martian inhabitants.
A new laser system captures the behavior of individual photons and uses advanced optics to deduce what's around the corner.
Physicists at the Lawrence Livermore National Laboratory in the National Ignition Facility have utterly decimated a previous record for the most powerful laser shot ever.
Unmanned aerial vehicles have seen extensive deployment in both Iraq and Afghanistan.
Lightning guns are often thought of as weapons of science fiction, relegated to the pages of magazines, movie screens and video games.
MIT researchers say they've developed a camera that can see round corners - useful for peeping toms and rescue workers.
Scientists have created the smallest-ever laser to work at room temperature, as well as one that doesn't waste a single photon.
Department of Energy scientists have built the world's hottest laser, delivering temperatures hotter than the corona of the sun.
It's a bit of a push as claims go: most satelites orbit at a distance of about 200 miles, compared with the 85-mile range of the S3 Krypton Series. Nevertheless, it's a bit more powerful than your average laser pointer.
Scientists, rather unbelievably, have created a functioning laser from a single living human kidney cell.
Thanks to the crisis in Libya, terms like "no fly zone," "air defense" and "anti-aircraft missiles" are bombarding the headlines once again with a vengeance.
