In principle, the dual-comb technique could detect an even wider range of gases over many kilometers. Accuracy in the measured atmospheric transmission is assured by the well-defined position of ...

Researchers at the University of Colorado Boulder have improved the gas sensing capabilities of optical frequency comb lasers ...

By providing a second dimension to the typical output of a frequency comb, the new technique efficiently packs more data into a given area without sacrificing precision, Diddams says. All light ...

Dual-comb spectroscopy, a powerful technique for precise spectroscopy over broad spectral bandwidths, has been mainly used for infrared linear absorption of small molecules in the gas phase.

In principle, the dual-comb technique could detect an even wider range of gases over many kilometers. Accuracy in the measured atmospheric transmission is assured by the well-defined position of ...

Hänsch, together with John Hall, was awarded the 2005 Nobel Prize in Physics for work including the frequency comb technique. Astronomers use instruments called spectrographs to spread the light ...
