Latest Frequency comb Stories
Astronomical instruments needed to answer crucial questions, such as the search for Earth-like planets or the way the Universe expands, have come a step closer with the first demonstration at the telescope of a new calibration system for precise spectrographs.
Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. The same NIST group also has shown that this type of laser, when used as a frequency combâ€”an ultraprecise technique for measuring different colors of lightâ€”could boost the sensitivity of astronomical tools searching for other Earthlike planets as...
Exhale on a cold winter day and you will see the water vapor coming out of your mouth. Light up your breath with a Nobel-Prize-related tool, and you could potentially detect trace amounts of over 1,000 compounds, some of which provide early warning signs of disease.
STOCKHOLM (Reuters) - Americans Roy Glauber and John Hall and Germany's Theodor Haensch won the 2005 Nobel Physics prize for their work in the field of optics, said the Royal Swedish Academy of Sciences on Tuesday.
The world's most accurate "ruler" made with extreme ultraviolet light has been built and demonstrated with ultrafast laser pulses by scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder.
