Noise-induced servo errors in optical clocks utilizing Rabi interrogation
T. Lindvall, A. E. Wallin, K. J. Hanhijärvi +1
We show that in optical clocks based on Rabi interrogation, both laser-frequency and magnetic-field flicker () noise with zero mean can lead to servo errors at the …
High-Accuracy Determination of Paul-Trap Stability Parameters for Electric-Quadrupole-Shift Prediction
T. Lindvall, K. J. Hanhijärvi, T. Fordell +1
The motion of an ion in a radiofrequency (rf) Paul trap is described by the Mathieu equation and the associated stability parameters that are proportional to the rf and dc electric…
First electrical White Rabbit absolute calibration inter-comparison
P. P. M. Jansweijer, N. A. D. Boukadida, K. Hanhijärvi +3
A time transfer link consisting of PTP White Rabbit (PTP-WR) devices can transfer time with sub-nanosecond accuracy. Originally White Rabbit devices were calibrated as a set of two…
Analysis of thermal radiation in ion traps for optical frequency standards
Miroslav Doležal, Petr Balling, Peter B R Nisbet-Jones +16
In many of the high-precision optical frequency standards with trapped atoms or ions that are under development to date, the AC Stark shift induced by thermal radiation leads to a…
Frequency comparison of Yb ion optical clocks at PTB and NPL via GPS PPP
J. Leute, N. Huntemann, B. Lipphardt +11
We used Precise Point Positioning, a well-established GPS carrier-phase frequency transfer method to perform a direct remote comparison of two optical frequency standards based on…
Broadband, unpolarized repumping and clearout light sources for Sr single-ion clocks
T. Fordell, T. Lindvall, P. Dubé +3
Future transportable optical clocks require compact and reliable light sources. Here, broadband, unpolarized repumper and state clearout sources for Sr+ single-ion optical clocks a…
