Absolute frequency measurement of the Hg transition with background-free saturation spectroscopy
Adam Linek, Piotr Morzyński, Marcin Witkowski
We report the development of a method for eliminating background-induced systematic shifts affecting precise measurements of saturation absorption signals. With this technique, we…
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…
Dual Hg-Rb magneto-optical trap
Marcin Witkowski, Bartlomiej Nagoorny, Rodolfo Munoz-Rodriguez +6
We present a two-species laser cooling apparatus capable of simultaneously collecting Rb and Hg atomic gases into a magneto-optical trap (MOT). The atomic sources, laser system, an…
Searching for topological defect dark matter with optical atomic clocks
Piotr Wcislo, Piotr Morzynski, Marcin Bober +4
The total mass density of the Universe appears to be dominated by dark matter. However, beyond its gravitational interactions at the galactic scale, little is known about its natur…
Absolute measurement of the - clock transition in neutral Sr over the 330 km-long stabilized fibre optic link
Piotr Morzynski, Marcin Bober, Dobroslawa Bartoszek-Bober +14
We report a stability below of two independent optical lattice clocks operating with bosonic Sr isotope. The value (429228066418008.3(1.9)(…
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…
