Stomach ulcer not only aches, it also fluoresce. Russian researchers believe that the brighter the fluorescence is, the less chances the patient has to do without the operation. view more (2005-02-22)
Paint-on laser could rescue computer chip industry
Researchers at the University of Toronto have created a laser that could help save the $200-billion dollar computer chip industry from a looming crisis dubbed the "interconnect bottleneck." view more (2006-04-18)
Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins. Like a line of silent ballet dancers, long-chain... view more... (2004-05-14)
The search for new applications for laser light beams
Light can blind or distort colours, or confuse one with chiaroscuros. But it can have greater usefulness if its properties, characteristics, how it is created, etcetera are better understood. view more (2006-05-30)
Laser blasts will reveal structures and dynamics of molecules in the fastest events in nature
A new £2 million Research Centre at the University of York will provide unprecedented information on how molecules change, helping scientists understand the structure and dynamics of liquids, proteins and even our DNA. The York Centre for Laser Spectroscopy and Photochemistry opened today (29 October 2003), will use ultra-short laser light... view more... (2003-10-27)
New nanotube coating enables novel laser power meter
The U.S. military can now calibrate high-power laser systems, such as those intended to defuse unexploded mines, more quickly and easily thanks to a novel nanotube-coated power measurement device developed at the National Institute of Standards and Technology (NIST). view more (2009-05-11)
BUSM researchers identify better laser for treating facial spider veins
Researchers from Boston University School of Medicine (BUSM) have concluded that the 940nm wavelength laser is superior for treating facial spider veins (telangiectasias) as compared to the 532nm wavelength laser. view more (2009-10-07)

Ultrafast lasers take 'snapshots' as atoms collide
Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide. view more (2005-10-21)
Helia Wraps-up Optical Coatings
A new Scottish multi-million pound photonics company is geared up for the future of telecommunications after securing a seven figure private investment deal. The investment has allowed Helia Photonics Ltd, a Heriot-Watt University spin-out to purchase the coatings division of Terahertz Photonics in a technology transfer deal, and say they are... view more...

Topical Papers in Biochemical Journal - Selective determination of mitochandrial chelatable iron in viable cells with a new fluorescent sensor
This paper by Petrat and colleagues marks an important advance in our understanding of the regulation of iron in the human body. Real-time changes in the concentration of the ionized form of iron (Fe2+) can now be monitored within the mitochondria of living cells for the first time, thanks to the technique described in this article. For some... view more... (2002-02-08)

Scientists at Yokohama National University in Japan have built a highly efficient room-temperature nanometer-scale laser that produces stable, continuous streams of near-infrared laser light. view more (2007-06-21)
Thermometer For Plasma
St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics. This device is a further step forward to controlled nuclear fusion. The device... view more... (2003-09-05)
Nine Countries Plan to Participate in the XFEL
An important milestone has been reached on the way towards the realization of the European X-ray laser XFEL: With France, Germany, Great Britain, Greece, Italy, Poland, Spain, Sweden, and Switzerland, nine countries have signed a Memorandum of Understanding in which they agree to jointly prepare the foundation of the facility. "Even if this... view more... (2005-01-24)
Experimental atomic clock uses ytterbium 'pancakes'
Scientists at the National Institute of Standards and Technology (NIST) working with Russian colleagues have significantly improved the design of optical atomic clocks that hold thousands of atoms in a lattice made of intersecting laser beams. view more (2006-03-07)
Lasers in car manufacture
Lasers play a key role in modern production - for such tasks as cutting sheet metal to size, welding containers and trimming circuit . But their potential is far from exhausted. The automobile industry is playing a pioneering role in the introduction of new laser types and machining processes. The Fraunhofer Institute for Laser Technology ILT in... view more... (1999-07-01)
