First international comparison of fountain primary frequency standards via a long distance optical fiber link
J. Guéna, S. Weyers, M. Abgrall +25
We report on the first comparison of distant caesium fountain primary frequency standards (PFSs) via an optical fiber link. The 1415 km long optical link connects two PFSs at LNE-S…
A tunable low-drift laser stabilized to an atomic reference
Tobias Leopold, Lisa Schmöger, Stefanie Feuchtenbeiner +6
We present a laser system with a linewidth and long-term frequency stability at the 50 kHz level. It is based on a Ti:Sapphire laser emitting radiation at 882 nm which is reference…
A clock network for geodesy and fundamental science
C. Lisdat, G. Grosche, N. Quintin +32
Leveraging the unrivaled performance of optical clocks in applications in fundamental physics beyond the standard model, in geo-sciences, and in astronomy requires comparing the fr…
Direct comparison of optical lattice clocks with an intercontinental baseline of 9 000 km
H. Hachisu, M. Fujieda, S. Nagano +9
We have demonstrated a direct frequency comparison between two lattice clocks operated in intercontinentally separated laboratories in real time. Two-way satellite…
A strontium lattice clock with inaccuracy and its frequency
Stephan Falke, Nathan Lemke, Christian Grebing +10
We have measured the absolute frequency of the optical lattice clock based on Sr at PTB with an uncertainty of using two caesium fountain clocks. This i…
