Realization of a time-scale with an accurate optical lattice clock
C. Grebing, A. Al-Masoudi, S. Dörscher +7
Optical clocks are not only powerful tools for prime fundamental research, but are also deemed for the re-definition of the SI base unit second as they now surpass the performance…
A Cs-Based Optical Frequency Measurement Using Cross-Linked Optical and Microwave Oscillators
Chr. Tamm, N. Huntemann, B. Lipphardt +5
We describe a measurement of the frequency of the 2S1/2(F = 0) - 2D3/2(F' = 2) transition of 171Yb+ at the wavelength 436 nm (frequency 688 THz), using a single Yb+ ion confined in…
Atomic trajectory characterization in a fountain clock based on the spectrum of a hyperfine transition
Nils Nemitz, Vladislav Gerginov, Robert Wynands +1
We describe a new method to determine the position of the atomic cloud during its interaction with the microwave field in the cavity of a fountain clock. The positional information…
Distributed cavity phase frequency shifts of the caesium fountain PTB-CSF2
S. Weyers, V. Gerginov, N. Nemitz +2
We evaluate the frequency error from distributed cavity phase in the caesium fountain clock PTB-CSF2 at the Physikalisch-Technische Bundesanstalt with a combination of frequency me…
