Getting warmer -- Leeds research brings terahertz closer to everyday use
A collaboration between the Universities of Leeds and Harvard has turned the heat up on terahertz technology, bringing a handheld terahertz device a step closer to reality. view more (2008-03-31)
New evidence for organic compounds in deep space
The mysterious spectral bands in the infrared of interstellar gas clouds in deep space originate from organic compounds. Research by the Nijmegen physicist Hans Piest confirms this. He has provided new experimental evidence for this almost 30-year-old problem in astronomy. Each molecule has specific wavelengths at which it can either absorb or... view more... (2002-04-18)
A sonic boom in the world of lasers
It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. view more (2009-06-18)
Atom 'noise' may help design quantum computers
As if building a computer out of rubidium atoms and laser beams weren't difficult enough, scientists sometimes have to work as if blindfolded: The quirks of quantum physics can cause correlations between the atoms to fade from view at crucial times. view more (2007-03-05)
Laser processes promise better artificial joints, arterial stents
Researchers are developing technologies that use lasers to create arterial stents and longer-lasting medical implants that could be manufactured 10 times faster and also less expensively than is now possible. view more (2009-09-16)
'Tornadoes' are transferred from light to sodium atoms
For the first time, tornado-like rotational motions have been transferred from light to atoms in a controlled way at the National Institute of Standards and Technology (NIST). view more (2006-11-10)
Nanocomposite labeled cancer cells can be targeted and destroyed using lasers
A nanocomposite particle can be constructed so that it has a mix of properties that would not otherwise happen in nature. By combining an organic matrix with metallic clusters that can absorb light, it is possible to incorporate such particles into cells and then destroy those targeted cells with a laser. view more (2007-05-21)
Laser microsurgery for tongue cancer is as effective as invasive open surgery according to new study
Transoral (through-the-mouth) laser surgery to remove cancer at the base of the tongue is as effective as more invasive open surgery and may improve quality of life according to a new study by Rush University Medical Center. view more (2009-07-21)
Record-setting laser may aid searches for Earthlike planets
Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. view more (2008-05-08)
Ultra-Intense Laser Blast Creates True 'Black Metal'
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black. view more (2006-11-22)
Computer vision for the blind
The white cane used by the blind as a travel aid may be universal, but it is not always adequate when it comes to pedestrian crossings. Although some crossings make a sound when it is safe to cross, many do not, and it is at these crossings that the blind need to know when the green man is showing. Adaptations of the white cane have been made,... view more... (2002-08-15)
New insights into how lasers cut flesh
Lasers are at the cutting edge of surgery. From cosmetic to brain surgery, intense beams of coherent light are gradually replacing the steel scalpel for many procedures. view more (2007-10-26)
Nano technique allows precise injection of living cells
Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells. view more (2007-06-18)
Harvard University engineers demonstrate laser nanoantenna
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. view more (2006-09-07)
'Tunable' network features coordinated frequency combs
A super stable fiber-optic network that can be tuned across a range of visible and near-infrared frequencies while synchronizing the oscillations of light waves from different sources has been demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-05-14)
Argonne scientists use lasers to align molecules
Protein crystallographers have only scratched the surface of the human proteins important for drug interactions because of difficulties crystallizing the molecules for synchrotron x-ray diffraction. view more (2008-05-14)
Laser tweezers sort atoms
Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up. view more (2006-07-13)
Scientists demonstrate highly directional semiconductor lasers
Applied scientists at Harvard University in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and... view more... (2008-07-28)
NIST laser-based method cleans up grubby nanotubes
Before carbon nanotubes can fulfill their promise as ultrastrong fibers, electrical wires in molecular devices, or hydrogen storage components for fuel cells, better methods are needed for purifying raw nanotube materials. view more (2006-12-26)
Astronomers use laser to take clearest images of the center of the Milky Way
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii. view more (2005-12-21)
