Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
First observation with global network of optical atomic clocks aimed for a dark matter detection
P. Wcisło, P. Ablewski, K. Beloy +19
We report on the first earth-scale quantum sensor network based on optical atomic clocks aimed at dark matter (DM) detection. Exploiting differences in the susceptibilities to the…
Absolute frequency determination of molecular transition in the Doppler regime at kHz level of accuracy
K. Bielska, S. Wojtewicz, P. Morzynski +7
We present absolute frequency measurement of the unperturbed P7 P7 O B-band transition with relative standard uncertainty of . We reached the level of accuracy…
Fibre-optic delivery of time and frequency to VLBI station
P. Krehlik, Ł. Buczek, J. Kołodziej +18
The quality of Very Long Baseline Interferometry (VLBI) radio observations predominantly relies on precise and ultra-stable time and frequency (T&F) standards, usually hydrogen mas…
Strontium optical lattice clocks for practical realization of the metre and secondary representation of the second
M. Bober, P. Morzyński, A. Cygan +17
We present a system of two independent strontium optical lattice standards probed with a single shared ultra-narrow laser. The absolute frequency of the clocks can be verified by t…
Absolute Frequency Measurement of Rubidium 5S-7S Two-Photon Transitions
Piotr Morzynski, Piotr Wcislo, Piotr Ablewski +9
We report the absolute frequency measurements of rubidium 5S-7S two-photon transitions with a cw laser digitally locked to an atomic transition and referenced to an optical frequen…
