A definition of the SI second based on several optical transitions

Jérôme Lodewyck

A new definition of the SI second based on optical transitions is expected to be adopted within the next 10 years. Several options for this redefinition are currently under conside…

Universal formalism for data sharing and processing in clock comparison networks

Jérôme Lodewyck, Rodolphe Le Targat, Paul-Eric Pottie +3

We present a mathematical framework adapted to the comparison of atomic clocks remotely connected by a complex network of optical or microwave links. This framework facilitates the…

Differential phase extraction in dual interferometers exploiting the correlation between classical and quantum sensors

M. Langlois, R. Caldani, A. Trimeche +2

We perform the experimental demonstration of the method proposed in [Phys. Rev. A 91, 063615 (2015)] to extract the differential phase in dual atom interferometers. From a single m…

A high-performance Raman-Ramsey Cs vapor cell atomic clock

Moustafa Abdel Hafiz, Grégoire Coget, Peter Yun +3

We demonstrate a high-performance coherent-population-trapping (CPT) Cs vapor cell atomic clock using the push-pull optical pumping technique (PPOP) in the pulsed regime, allowing…

Influence of chirping the Raman lasers in an atom gravimeter: phase shifts due to the Raman light shift and to the finite speed of light

B. Cheng, P. Gillot, S. Merlet +1

We present here an analysis of the influence of the frequency dependence of the Raman laser light shifts on the phase of a Raman-type atom gravimeter. Frequency chirps are applied…

Characterization of Cs vapor cell coated with octadecyltrichlorosilane using coherent population trapping spectroscopy

Moustafa Abdel Hafiz, Vincent Maurice, Ravinder Chutani +5

We report the realization and characterization using coherent population trapping (CPT) spectroscopy of an octadecyltrichlorosilane (OTS)-coated centimeter-scale Cs vapor cell. The…
