Optical Atomic Clock Comparison through Turbulent Air
Martha I. Bodine, Jean-Daniel Deschênes, Isaac H. Khader +32
We use frequency comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic cloc…
Measurement of the impact of turbulence anisoplanatism on precision free-space optical time transfer
W. C. Swann, M. I. Bodine, I. Khader +4
Future free-space optical clock networks will require optical links for time and frequency transfer. In many potential realizations of these networks, these links will extend over…
Synchronization of Distant Optical Clocks at the Femtosecond Level
Jean-Daniel Deschenes, Laura C. Sinclair, Fabrizio R. Giorgetta +6
The use of optical clocks/oscillators in future ultra-precise navigation, gravitational sensing, coherent arrays, and relativity experiments will require time comparison and synchr…
Frequency Comb-Based Remote Sensing of Greenhouse Gases over Kilometer Air Paths
Gregory B. Rieker, Fabrizio R. Giorgetta, William C. Swann +10
We demonstrate coherent dual frequency-comb spectroscopy for detecting variations in greenhouse gases. High signal-to-noise spectra are acquired spanning 5990 to 6260 cm^-1 (1600 t…
Operation of an optically coherent frequency comb outside the metrology lab
Laura C. Sinclair, Ian Coddington, William C. Swann +4
We demonstrate a self-referenced fiber frequency comb that can operate outside the well-controlled optical laboratory. The frequency comb has residual optical linewidths of < 1 Hz,…
Optical two-way time and frequency transfer over free space
Fabrizio R. Giorgetta, William C. Swann, Laura C. Sinclair +3
The transfer of high-quality time-frequency signals between remote locations underpins a broad range of applications including precision navigation and timing, the new field of clo…
