Continuous optical generation of microwave signals for fountain clocks
Burghard Lipphardt, Patrick Walkemeyer, Michael Kazda +2
For the optical generation of ultrastable microwave signals for fountain clocks we developed a setup, which is based on a cavity stabilized laser and a commercial frequency comb. T…
Advances in the accuracy, stability, and reliability of the PTB primary fountain clocks
S. Weyers, V. Gerginov, M. Kazda +4
Improvements of the systematic uncertainty, frequency instability, and long-term reliability of the two caesium fountain primary frequency standards CSF1 and CSF2 at PTB (Physikali…
Phase Analysis for Frequency Standards in the Microwave and Optical Domains
M. Kazda, V. Gerginov, N. Huntemann +2
Coherent manipulation of atomic states is a key concept in high-precision spectroscopy and used in atomic fountain clocks and a number of optical frequency standards. Operation of…
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…
