WASHINGTON, Nov. 12, 2009 -- Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually.
WASHINGTON, Sept. 18 -- Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. Researchers in Australia have now demonstrated the first laser built with diamonds that has comparable efficiency to lasers built with other materials.
In what may prove to be a major development for scientists in fields ranging from forensics to quantum communications, researchers at the National Institute of Standards and Technology (NIST) have developed a new, highly sensitive, low-cost technique for measuring light in the near-infrared range.
WASHINGTON, Aug. 18 -- A group of researchers in Australia and Taiwan has developed a new way to analyze the health of human teeth using lasers.
SALT LAKE CITY, Aug. 17, 2009 -- University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures from tsunamis.
Chestnut Hill, Mass. (July 31, 2009) -- Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard.
Physicists at New York University have developed a technique to record three-dimensional movies of microscopic systems, such as biological molecules, through holographic video. The work, which is reported in Optics Express, has potential to improve medical diagnostics and drug discovery.
Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect.
Sliced light is how we communicate now. Millions of phone calls and cable television shows per second are dispatched through fibers in the form of digital zeros and ones formed by chopping laser pulses into bits.
