’Molecular Fingerprinting’ Improved for Gas Detection
GAITHERSBERG, Md., Oct. 21, 2010 — Scientists have demonstrated a laser-based “molecular fingerprinting” technique that can differentiate billions of hydrogen-containing and other molecules from one another in gas in just 30 seconds or less — a performance that is suitable for breathalyzers for diagnosing disease, measuring trace gases in the atmosphere, detecting security threats and other applications. The collaborating scientists, including those from JILA, jointly operated by the National Institute of St...

Color of Single Photons Changed
GAITHERSBURG, Md., Oct. 18, 2010 — The conversion of near-infrared 1300-nm-wavelength single photons emitted from a true quantum source — a semiconductor quantum dot — to a near-visible wavelength of 710 nm was demonstrated for the first time. The ability to change the color of...
Microscopy with Self-reconstructing Laser Beams
FREIBURG, Germany, Oct. 18, 2010 — Researchers at the University of Freiburg are working to overcome a key problem of light microscopy in cell biology -- light-scattering cell clusters, which repeatedly destroy the laser beam’s profile and render some of the cells nearly invisible--...
FILAS Deadline Fast Approaching
ISTANBUL, Turkey, Oct. 15, 2010 — The deadline for submitting research and work to the new Optical Society of America topical meeting Fiber Laser Applications (FILAS) is Monday, Oct. 18, 2010, noon EDT (16.00 GMT). The Optical Society of America (OSA) is launching the meeting to...
