Laser scientists take step towards making fusion energy a reality
Scientists from the UK and Japan may have taken us one step further to the reality of fusion energy with a new answer to an old problem. Research by Dr Ryosuke Kodama and his colleagues at Osaka University, Japan and the UK team published in Nature on Thursday 23 August details a new technique for using lasers to start the fusion reaction. The... view more... (2001-08-20)
At the limits of the photoelectric effect
By way of the classical photoeffect, Einstein proved in 1905 that light also has particle character. However, with extremely high light intensities, remarkable things happen in the process. view more (2009-04-24)
Stevens faculty release study on free-space optical communication in Optics Express
Three members of the faculty at Stevens Institute of Technology recently collaborated on a paper focusing on free-space optical communication, which appears in the latest issue of Optics Express, a premiere optics journal currently in circulation. view more (2009-03-18)
Quantum goes massive
An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale. view more (2009-07-16)

Finely tuned laser strikes the right chord
Pulses of laser light can make molecules react in ways that are impossible using classical test-tube chemistry. Molecules vibrate, and each molecule has its own "tone," its own "melody." It's a question of finding the right key, and that is something that a "smart" laser beam can do. It can find its way to the... view more... (2002-05-30)
Researchers demonstrate single molecule absorption spectroscopy
A powerful new tool for probing molecular structure on surfaces has been developed by researchers at the University of Illinois at Urbana-Champaign. view more (2005-12-21)
Acupuncture more effective than massage for chronic neck pain
Acupuncture is an effective short term treatment for patients with chronic neck pain, but there is only limited evidence for its long term effects after five treatments, concludes research in this week's BMJ. A total of 177 patients with chronic neck pain were randomly allocated to five treatments over three weeks. Fifty-six patients received... view more... (2001-06-27)
New laser technique that strips hydrogen from silicon surfaces
A team of researchers have achieved a long-sought scientific goal: using laser light to break specific molecular bonds. The process uses laser light, instead of heat, to strip hydrogen atoms from silicon surfaces, a key step in the manufacture of computer chips and solar cells. view more (2006-05-19)
Researcher investigates new developments in laser and sensor technology
Scientists hope that research being conducted in Binghamton University's Department of Physics, Applied Physics and Astronomy will create lasers that work at wavelengths currently inaccessible. view more (2008-02-22)
Warm water vibrates for longer
Dutch researcher Arjan Lock has investigated the behaviour of vibrating water molecules. Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives shorter at higher temperatures. Lock studied the OH-stretch... view more... (2004-02-05)
Atomic fountain clocks are becoming still more stable
They are at present the most accurate clocks in the world: Caesium fountain clocks furnish the second accurate to 15 places after the decimal point. Until they reach this accuracy, caesium fountain clocks, however, need a certain measurement time. view more (2009-03-18)
Next Step to the Quantum Computer
Physicists from the University of Bonn have succeeded in taking a decisive step forward towards processing quantum information with neutral atoms: in the latest issue of the 'Physical Review Letters' vol. 93 (2004) they describe how they managed to set up a quantum register experimentally. Their next aim is to construct a quantum gate in which two... view more... (2004-10-08)
New technique measures ultrashort laser pulses at focus
Lasers that emit ultrashort pulses of light are used for numerous applications including micromachining, microscopy, laser eye surgery, spectroscopy and controlling chemical reactions. But the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. view more (2008-05-09)
Laser pulses control single electrons in complex molecules
Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. view more (2009-09-02)
Oregon physicists don't flip spin but find possible electron switch
University of Oregon researchers trying to flip the spin of electrons with laser bursts lasting picoseconds (a trillionth of a second) instead found a way to manipulate and control the spin -- knowledge that may prove useful in a variety of new materials and technologies. view more (2008-05-28)
Revamped experiment could detect elusive particle, physicists say
An experiment called "shining light through walls" would seem hard to improve upon. But University of Florida physicists have proposed a way to do just that, a step they say considerably improves the chance of detecting one of the universe's most elusive particles, a candidate for the common but mysterious dark matter. view more (2007-04-26)
The Light Is Fighting Cancer
