Two Unique Plating Techniques Combine to Boost IR Gas Sensor and YAG Laser Performance NEW YORK, July 14, 2014 /PRNewswire/ -- A new process that combines a gold plating technique developed for the Space Program's YAG Laser Pump Cavities with the age-old manufacturing technique of electroforming, is now dramatically increasing the sensitivity of infrared gas analyzers and sensors--products that have long used infrared light to detect CO, CO2 and many other trace gases in the...

At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler. Lan Yang, PhD, associate professor of electrical and systems engineering, and her collaborators...

A Feeling For The 'Light' Wave

Max-Planck-Institute of Quantum Optics A team in the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institute of Quantum Optics has taken another step toward the achievement of complete control over the waveform of pulsed laser light. Together with colleagues based at LMU and the Technische Universität München (TUM), they have constructed a detector which provides a detailed picture of the waveforms of laser pulses that last for a few femtoseconds (1 fs = 10-15 seconds)....

Development of electronics and communication requires a hardware base capable for increasingly larger precision, ergonomics and throughput. For communication and GPS-navigation satellites, it is of great importance to reduce the payload mass as well as to ensure the signal stability. Last year, researchers from the Moscow State University (MSU) together with their Swiss colleagues from EFPL performed a study that can induce certain improvements in this direction. The scientists demonstrated...

Ten Times More Throughput On Optic Fibers

Ecole Polytechnique Fédérale de Lausanne EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers; Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology. However, their capacity is limited, because the...

Intense 2-color Double X-ray Laser Pulses Generated For First Time
2013-12-04 12:47:43

RIKEN A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are very powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions. SACLA is one of only two facilities in the world to...

Word of the Day
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
