Trumpf Acquires Segments of Fisba
Mar 1, 2008 — Trumpf Laser GmbH + Co. KG of Ditzingen, Germany, has acquired the laser plastic welding and selective laser soldering segments of Fisba Optik AG of St. Gallen, Switzerland, a producer of micro-optics for beam formation of laser diodes and custom laser modules. The German company plans to offer a wider range of laser applications to its customers, including proprietary systems for laser welding and soldering.
Northrop Grumman Awarded MDA Contract
Mar 1, 2008 — Northrop Grumman Corp. of Redondo Beach, Calif., has received a contract from the Missile Defense Agency (MDA) for the second phase of a program to develop the Advanced Track Illuminator Laser. The 5 1/2-year project aims to create a 6-kW-class...
White Light from a Near-UV Laser Diode
Mar 1, 2008 — Techniques for producing white light from LED methods vary, but most involve mixing blue LED light with yellow phosphor to achieve what the human eye perceives as white. However, the white light is not stable, and its luminous efficacy decreases as...
Thermal Sensing with Short-Wave Infrared Detectors
Mar 1, 2008 — Because glass is not transparent at mid- and long-infrared wavelengths, it stops current thermal detectors cold. Consequently, regular glass lenses cannot be used for these thermal imagers, and thermal imagers cannot peer through the window of a...
Making Slow Light Go Slower
Mar 1, 2008 — A crucial part of optical signal processing is buffering and storage — sometimes a signal has to wait a while until the system is ready for it. Although this is readily accomplished electronically, it is more of a challenge optically. One approach...
Incoherent Detection of Airborne Pollutants
Mar 1, 2008 — Researchers and regulators have a new tool when it comes to detecting airborne pollutants and pinpointing their source, thanks to a group from University College Cork in Ireland. The group’s members have demonstrated an incoherent broadband...
Infrared Spectroscopy Checks on Diet Drinks
Mar 1, 2008 — Sugar is sweet but aspartame is sweeter, permitting it to be used as a low-calorie sugar substitute in diet soft drinks and other foods. However, some people believe that aspartame’s metabolic by-products strike a sour note and can cause health...
Spectroscopy Can Help Bakers Make Bread
Mar 1, 2008 — When bread dough rises in a small amount of time, the yeast does not produce much carbon dioxide gas, resulting in bread that is too flat and too hard. Longer rise times, however, result in bread that is too fluffy. Bakers currently rely on personal...
Adding Teeth to Spectroscopic Detection
Mar 1, 2008 — With conventional broadband spectroscopy techniques, detecting optical frequencies can be performed to a resolution of ~10 MHz. Now, however, researchers at the National Institute for Standards and Technology (NIST) in Boulder, Colo., have devised a...
Getting Semiconductors Ready to Take a Spin
Mar 1, 2008 — For semiconductors, the hope is that everything will not be just about electron charge in the future. Instead, having devices also exploit electron spin — resulting in new kinds of memory and logic chips — is a goal of spintronics, the spin-based...
Speedy and Colorful Terahertz Scanning
Mar 1, 2008 — When it comes to nondestructive screening and testing, terahertz time-domain spectroscopic imaging offers significant advantages but one considerable drawback. Lying between infrared and microwave wavelengths, terahertz waves can penetrate a wide...
Fighting Counterfeiting with the Basics
Mar 1, 2008 — The best way to spot a fake is to check its true colors. Identifying counterfeit commercial goods may be easier in the future, thanks to Effendi Widjaja and Marc V. Garland of the Singapore-based Institute of Chemical and Engineering Sciences, who...
The Anatomy of a Smudge
Mar 1, 2008 — Industrial and household contaminants abound, but how these toxic substances get from their source onto human hands is less than certain. Of course, it usually requires touch, but does a moist hand pick up contaminants better than a dry one? Is...
Solar Energy Project to be Launched in the United Kingdom
Mar 1, 2008 — Durham University in the UK will lead a four-year solar energy research project with a focus on producing thin-film photovoltaic cells. The £6.3 million study, known as PV-21, will get under way this April. The project’s goal is to make solar...
Salvador Imaging Awarded Contract from Raytheon
Mar 1, 2008 — Salvador Imaging, a subsidiary of Photon Dynamics Inc. of San Jose, Calif., has been awarded a contract by Raytheon Co. of Waltham, Mass., to supply high-performance surveillance cameras for a combat-proven, multiuse imaging system. The system...
Crystal Systems Receives $250K for Crystal Growth Project
Mar 1, 2008 — Crystal Systems Inc. of Salem, Mass., has received $250,000 from the French Institute de la Lumiere Extreme project. The funding will be used to scale up the heat exchange method process of crystal growth from 6 to 8 in. in diameter, for use in the...
Road Map for European Photonics Available
Mar 1, 2008 — The Merging Optics & Nanotechnologies (MONA) project based in Grenoble, France, has published “A European Roadmap for Photonics and Nanotechnologies,” a market report resulting from a two-year project funded by the European Commission to bridge...
