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 comb"”an ultraprecise technique for measuring different colors of light"”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. In a new paper, a team led by Jun Ye, a physicist at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder, has demonstrated an optical technique for...

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 trio won the prize "for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique," the Academy said, announcing the winners of the 10 million crown ($1.29 million) prize.

NIST -- 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. The new device, which consistently generates pulses of light lasting just femtoseconds (quadrillionths of a second, or millionths of a billionth of a second) in the ultraviolet region of the electromagnetic...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
