Universal formalism for data sharing and processing in clock comparison networks
Jérôme Lodewyck, Rodolphe Le Targat, Paul-Eric Pottie +3
We present a mathematical framework adapted to the comparison of atomic clocks remotely connected by a complex network of optical or microwave links. This framework facilitates the…
Simple and compact diode laser system stabilized to Doppler-broadened iodine-lines at 633 nm
Florian Krause, Erik Benkler, Christian Nölleke +2
We present a compact iodine-stabilized laser system at 633 nm, based on a distributed-feedback laser diode. Within a footprint of cm the system provides 5 mW of f…
Coherent laser spectroscopy of highly charged ions using quantum logic
P. Micke, T. Leopold, S. A. King +6
Precision spectroscopy of atomic systems is an invaluable tool for the advancement of our understanding of fundamental interactions and symmetries. Recently, highly charged ions (H…
Optical frequency ratio of a single-ion clock and a lattice clock
Sören Dörscher, Nils Huntemann, Roman Schwarz +6
We report direct measurements of the frequency ratio of the 642 THz -- electric octupole transition in and the 429 THz…
Coherent excitation of the highly forbidden electric octupole transition in Yb
Henning A. Fürst, Chih-Han Yeh, Dimitri Kalincev +7
We report on the first coherent excitation of the highly forbidden electric octupole (E3) transition in a single trapped Yb ion, an…
Long term measurement of the Sr clock frequency at the limit of primary Cs clocks
R. Schwarz, S. Dörscher, A. Al-Masoudi +7
We report on a series of 42 measurements of the transition frequency of the 429~THz (5s)~S--(5s5p)~P line in Sr taken over three years from 2017 to 2019.…
