Journal ArticleDOI
Frequency Ratio of Al+ and Hg+ Single-Ion Optical Clocks; Metrology at the 17th Decimal Place
Till Rosenband,David Hume,Piet O. Schmidt,Chin-Wen Chou,A. Brusch,Luca Lorini,Windell H. Oskay,Robert E. Drullinger,Tara M. Fortier,Jason Stalnaker,Scott A. Diddams,William C. Swann,Nathan R. Newbury,Wayne M. Itano,David J. Wineland,J. C. Bergquist +15 more
TL;DR: Repeated measurements during the past year yield a preliminary constraint on the temporal variation of the fine-structure constant α of α ofbatchmode, a regime of operation for atomic clocks based on optical transitions, promising even higher performance.
Journal ArticleDOI
Dual-comb spectroscopy
TL;DR: This review describes dual-comb spectroscopy and summarizes the current state of the art and suggests that frequency comb technology will continue to mature and could surpass conventional broadbandSpectroscopy for a wide range of laboratory and field applications.
Journal ArticleDOI
Rapid and precise absolute distance measurements at long range
TL;DR: In this paper, the authors demonstrate a coherent laser ranging system that combines the advantages of time-of-flight and interferometric approaches to provide absolute distance measurements, simultaneously from multiple reflectors, and at low power.
Journal ArticleDOI
Coherent multiheterodyne spectroscopy using stabilized optical frequency combs.
TL;DR: The broadband, coherent nature of narrow-linewidth fiber frequency combs is exploited to measure the full complex spectrum of a molecular gas through multiheterodyne spectroscopy, and the measured phase spectrum agrees with the Kramers-Kronig transformation of the absorption spectrum.
