RESEARCH & TECHNOLOGY NEWS
Tunable Wavelengthsby Four-Wave Mixing
Aug 1, 2008 — Photonics specialists from Helsinki University of Technology and from Arctic Photonics of Jorvas, both in Finland, are using four-wave mixing (FWM) to produce tunable narrowband light in a microstructured optical fibre. The light has a pulse shorter than 1 ns, peak power of tens of watts, with signal wavelengths from blue to orange. It would be a good source for fluorescence spectroscopy. To produce this narrowband light, photons at 532 and 1064 nm from an Nd:YAG laser pass through a lens...
UIowa to Assess Lab Damage
IOWA CITY, Iowa, June 18, 2008 -- It will be months before the full extent of flood damage sustained by the Iowa Advanced Technology Laboratories (IATL) is known, a University of Iowa official said Wednesday. The facility remains closed, with water from the nearby Iowa River in its...
Elbit Systems, Technion Partner on Eye-Tracking Research
Jun 16, 2008 — Defense electronics company Elbit Systems Ltd. of Haifa, Israel, and the Haifa-based Israel Institute of Technology (Technion) have signed a joint vision systems research agreement, under which Elbit will award grants to selected Technion...
Detecting Nanoparticles in a Flame
Jun 1, 2008 — A team of scientists from Università di Napoli and from Istituto di Ricerche sulla Combustione, both in Italy, and from Lund University in Sweden has directly measured combustion-generated nanometer-size organic carbon particles within a propane...
Laser Analysis of Strawberries
Jun 1, 2008 — Phenolic compounds in fruits and vegetables enhance their nutritional value, so it is useful to identify and quantify the various native compounds. Scientists from Leibniz Institute for Agricultural En- gineering Potsdam-Bornim and from Technical...
Laser Sorts Moving Droplets in Lab on a Chip
Jun 1, 2008 — A paper by three physicists from Université Bordeaux I in France describes a new and highly effective method of sorting and routing nanolitre droplets flowing through microchannels. The technique will be useful in chemical microreactors and...
Observing Laser-Shocked Tin Substrates
Jun 1, 2008 — When a shock wave generated by a laser beam or similar concentrated force bounces off a free surface, the material can undergo shock-induced fragmentation. Although commonly encountered in engineering and physics, the phenomenon remains poorly...
Understanding Smog by Measuring Light Absorption
Jun 1, 2008 — Haze lingering over cities may look fairly similar from place to place, but its composition can vary greatly. In some regions, industrial coal smoke predominates, whereas in others, automotive exhaust makes significant contributions. Researchers...
Northrop Grumman, UCF Ink Development Deal
May 22, 2008 — Defense contractor Northrop Grumman Corp. announced today it is forming a partnership with the University of Central Florida in Orlando to develop advanced optic and photonic technologies for military and defense applications. Under the five-year...
Active Multipass Geometry Boosts Pulse Energy
Apr 1, 2008 — Scientists from the University of Konstanz and from Trumpf Laser GmbH + Co. KG in Schramberg, both in Germany, have achieved pulse energies of more than 13 μJ from a thin-disc laser operating in air. These ultrashort pulses have applications in...
Diffractive Fluorescence Multiplex Assay
Apr 1, 2008 — A 14-member team from the University of Southampton and from the Rutherford Appleton Laboratory in Didcot, both in the UK, has combined microscopic bar codes and fluorescent biomolecules in a rapid, noninvasive assay with high encoding capacity. The...
Interferometer Investigates MEMS Vibrations
Apr 1, 2008 — Two scientists from Helsinki University of Technology in Finland have developed an instrument that probes surface vibrations of frequencies up to 6 GHz, detecting amplitudes down to 1 pm with a lateral resolution better than 1 μm. It measures...
NIR Spectroscopy Monitors Wood
Apr 1, 2008 — A team from the Competence Centre for Wood Composites and Wood Chemistry in Linz and from the University of Natural Resources and Applied Life Sciences Vienna, both in Austria, and from Technical University of Munich, has shown that near-infrared...
Photoacoustic Shear Waves in Gold Nanocrystals
Apr 1, 2008 — Scientists from Université du Mains in Le Mans and from Université de Caen, both in France, and from Massachusetts Institute of Technology in Cambridge, Mass., USA, have generated and detected picosecond acoustic shear waves in gold films. The...
Optical Tech Topic of Talks
SAN DIEGO, Feb. 15, 2008 -- Getting the most out of limited wireless bandwidth, ratcheting up data rates, new routes on the information superhighway, and a new view of the electromagnetic spectrum are some of the topics that will be covered in research presentations during the...

Pirelli Forms Photonics Group
MILAN, Italy, Feb. 4, 2008 -- The Pirelli Group announced it will form a new company by integrating the photonics work of its Broadband Solutions business with the photonics-related research and development activities of the optical innovation division of Pirelli Labs. The...
LEDs Provide Stable Spectroscopic Light Sources
Feb 1, 2008 — To estimate the concentration of various species in plasmas, scientists frequently employ broadband absorption spectroscopy. The xenon arc or deuterium lamps used as light sources in the devices, however, display high spatial and spectral...
Using Femtosecond Lasers in Multiplex Spectroscopy
Feb 1, 2008 — When conducting broadband molecular spectroscopy, researchers should use a high-brightness light source to obtain optimum results. Spectrometers used for analysis in the mid-infrared region, especially, should have high sensitivity, resolution and...
Beckman Coulter Inks Biomedical R&D, Licensing Deals
Jan 22, 2008 — Beckman Coulter Inc. of Fullerton, Calif., a manufacturer of biomedical testing instrument systems, tests and supplies that simplify and automate laboratory processes, announced this week it will launch a four-year, molecular diagnostics...
Aculight Promotes Robert Afzal, Hires CFO
Nov 9, 2007 — Laser maker Aculight Corp. of Bothell, Wash., announced this week that Robert Afzal, PhD, formerly director of technology development, has been promoted to vice president of research and development. Prior to joining Aculight a year ago, Afzal was...
SPIE to Offer Free Digital Library Access to Selected Countries
Sep 21, 2007 — SPIE has announced an agreement with the International Network for the Availability of Scientific Publications (INASP) to help meet the information needs of scientists in more than 30 countries that are rebuilding research capacity and...
