The knee op that helps free the knees up
Most people over the age of 30 have some sort of problem with their knees making walking, running or playing sport uncomfortable, and thousands of people each year have surgery to remove damaged cartilage from within their knees. view more (2000-01-20)
Diamonds are a laser's best friend
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. view more (2009-09-21)
Laser therapy can aggravate skin cancer
High irradiances of low-level laser therapy (LLLT) should not be used over melanomas. view more (2009-11-20)
New unifying theory of lasers advanced by physicists
Researchers at Yale and the Institute of Quantum Electronics at ETH Zurich have formulated a theory that, allows scientists to better understand and predict the properties of both conventional and non-conventional lasers, according to a recent article in Science. view more (2008-05-28)
Blue laser - the alpha and the omega
The future of DVD is blue. New, low-cost optical laser technology generates short-wavelength beams. At the other end of the beam are detector heads that will soon contain arrays of up to 25 sensors. Two Fraunhofer Institutes are taking the lead at both ends of the spectrum. Man's appetite seems to be insatiable. In the dark ages, packing away... view more... (2004-05-14)
Researchers at UC-Santa Barbara have built the world's first mode-locked silicon evanescent laser
Researchers at UC Santa Barbara have announced they have built the world's first mode-locked silicon evanescent laser, a significant step toward combining lasers and other key optical components with the existing electronic capabilities in silicon. view more (2007-08-22)
New Laser-Based Imaging for Early Diagnosis of Rheumatoid Arthritis
Study Documents Imaging Technique’s Accuracy in Detecting the Course of Finger Joint Inflammation view more (2002-04-24)
Scientists demonstrate laser with controlled polarization
Applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, lasers in which the direction of oscillation of the emitted radiation, known as polarization, can be designed and controlled at will. view more (2009-04-13)
A first experiment with the new "free-electron laser"
An international group of scientists has published first experiments carried out using the new soft X-ray free-electron laser (FEL) at the research center DESY (Nature, vol 420, p 482-485 and p 467). Using small clusters of noble gas atoms, for the first time, researchers studied the interaction of matter with intense X-ray radiation from an FEL... view more... (2002-12-05)
Sewer sensors examine the parts the inspectors cannot reach
A remote control sensing device is being developed to detect defects in sewer walls. Using both ultrasound and laser light, digital information on the condition of the sewer walls is fed back to a computer which can be programmed to spot problems. The research is being carried out by a team in the Department of Mechanical Engineering at King's... view more... (2002-10-10)
PTB Terahertz calibration satisfies US laser manufacturer
Terahertz radiation still lies in a metrological no man's land - a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. view more (2009-11-06)
High Power Laser for Ultraviolet Light
An international team of scientists at the research center DESY recently succeeded in obtaining the maximum light amplification from a "free electron laser" (FEL) for ultraviolet radiation. The electron laser produced an amplification of 10 million - this corresponds to the theoretically expected peak performance for such a device and presents a... view more... (2001-09-19)
UT Southwestern plastic surgeons deploy new carbon dioxide-based fractional laser
UT Southwestern Medical Center plastic surgeons are among a handful in the nation deploying a new type of laser that goes deeper into the skin to help reduce wrinkles, tighten surface structures and treat pigmentation differences. view more (2008-02-13)
Laser Instead Of A Diamond Saw
St. Petersburg physicists have developed a plant that allows to cut sapphire crystals into almost ideally smooth plates being fractions of millimeter thick. The approach suggested by the researchers fundamentally differs from the traditional one. They suggest that sapphire should not be sawn by a saw, but split by laser. view more (2004-10-22)
Laser sets records in power and energy efficiency
The rise in global terrorism in recent years has brought significant attention to the needs for more advanced sensors and defense technologies to protect civilians and soldiers. view more (2007-07-24)
Electron self-injection into an evolving plasma bubble
Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. view more (2009-11-03)
Ultra-fast, ultra-intense laser has clean-cut advantage
Many people equate lasers with a sci-fi battle in a galaxy far, far away or, closer to home, with grocery store scanners and compact disc players. view more (2008-03-14)
Compact, wavelength-on-demand Quantum Cascade Laser chip offers ultra-sensitive chemical sensing
Engineers from Harvard University have demonstrated a highly versatile, compact and portable Quantum Cascade Laser sensor for the fast detection of a large number of chemicals, ranging from infinitesimal traces of gases to liquids, by broad tuning of the emission wavelength. view more (2007-12-04)
New laser research could improve oil exploration success
CSIRO Petroleum and German-based research centre Laser Zentrum Hannover eV (LZH) are collaborating in a project that could save millions of dollars in oil exploration and introduce new Australian geochemical and petroleum analysis techniques to Europe. view more (2005-02-06)
Scientists at the University of the Basque Country succeed in cooling solid material with laser
A team of researchers at the University of the Basque Country (UPV/EHU) have experimentally demonstrated something that other scientists have been trying to achieve for decades: the cooling of erbium-doped materials with laser light. view more (2006-07-27)
