To most people, the word "ceramics," refers to opaque clay flower pots or translucent porcelain tea cups. But not all ceramics block or scatter light. Gary L. Messing, distinguished professor of ceramic science and engineering, and his group at Pennsylvania State University, are developing a brand new class of ceramics that are so pure and perfectly transparent, they can be used as a substitute for crystals in solid-state lasers.
The anisotropy imaging technique is now available for the serial equipment of the LSM 710 laser scanning microscope from Carl Zeiss. It supplements the special imaging techniques such as RICS (Raster Image Correlation Spectroscopy) and FCS (Fluorescence Correlation Spectroscopy) already possible with the LSM 710.
Two common strains of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, were virtually eradicated in the laboratory by exposing them to a wavelength of blue light, in a process called photo-irradiation that is described in a paper published online ahead of print in Photomedicine and Laser Surgery.
Surgeons at Northwestern Memorial Hospital are among the first in the country to use a new micro-laser, which uses light energy in place of a cutting tool to remove complicated brain and spine tumors. The technique offers greater precision and efficiency during surgery, reducing the incision size, surgery time and patient recovery period following surgery.
University of Colorado at Boulder physics Distinguished Professor Margaret Murnane has been named a National Security Science and Engineering Faculty Fellow by the U.S. Department of Defense.
Bookham, Inc. (NASDAQ: BKHM), a provider of optical components for industrial applications, has launched a high power multi-emitter pump module capable of delivering 25W out of a 105um fiber with 0.15NA. The product meets fiber laser manufacturers' demands for increased output power and brightness, compact pump configurations, and reduced overall system cost.
Alfalight, Inc., a leading supplier of highly efficient high-power diode lasers, announced today the first details of its breakthrough Surface-Emitting Distributed Feedback (SE-DFB) laser diode technology. This technology uses a significantly different approach at the wafer level to provide a lower-cost system solution with enhanced brightness and ruggedness compared to the edge-emitting laser technology.
A research associate at the U.S. Air Force Academy's Laser and Optics Research Center here is developing a new capability that will allow satellites to be seen and see clearer.
The Canadians are gathering at Photonics West 2009 in San Jose, CA with OCRI representatives to build on what a new industry report says is a shining success. In its survey entitled "Illuminating a World of Opportunity," the Canadian Photonics Consortium states Canada has 370 photonics companies employing some 20,000 people who collectively generate close to $4.5 billion annually, with approximately 85% from exports including 50% to the U.S.
Bookham, Inc. (Nasdaq: BKHM), a provider of optical components for industrial applications, has achieved an output power of 200W with a 10mm laser diode bar - believed to be the industry's most powerful commercially available continuous wave (CW) single bar product.
