Microcell CPT atomic clock using laser current-actuated power modulation with 10 range stability at 1 day
Carlos Manuel Rivera-Aguilar, Andrei Mursa, Clément Carlé +5
We present a coherent-population trapping (CPT) microcell atomic clock using symmetric auto-balanced Ramsey (SABR) spectroscopy. The pulsed SABR sequence is applied through direct…
Preliminary characterization of a surface electrode Paul trap for frequency metrology
Josipa Madunic, Lucas Groult, Bachir Achi +7
We are developing a single-ion optical clock based on a surface-electrode (SE) trap that we will operate with Yb ions on the electric quadrupole transition at 435.5 nm.…
On the reduction of gas permeation through the glass windows of micromachined vapor cells using AlO coatings
Clément Carlé, Andrei Mursa, Petri Karvinen +5
Stability and precision of atomic devices are closely tied to the quality and stability of the internal atmosphere of the atomic vapor cells on which they rely. Such atmosphere can…
Reduction of helium permeation in microfabricated cells using aluminosilicate glass substrates and AlO coatings
C. Carlé, S. Keshavarzi, A. Mursa +10
The stability and accuracy of atomic devices can be degraded by the evolution of their cell inner atmosphere. Hence, the undesired entrance or leakage of background or buffer gas,…
Heating rate measurement and characterization of a prototype surface-electrode trap for optical frequency metrology
Thomas Lauprêtre, Bachir Achi, Lucas Groult +4
We present the characterization of a prototype surface-electrode (SE) trap as a first step towards the realization of a compact, single-ion optical clock based on Yb. The use o…
Laser-actuated hermetic seals for integrated atomic devices
Vincent Maurice, Clément Carlé, Shervin Keshavarzi +8
Atomic devices such as atomic clocks and optically-pumped magnetometers rely on the interrogation of atoms contained in a cell whose inner content has to meet high standards of pur…
Light-shift mitigation in a microcell-based atomic clock with Symmetric Auto-Balanced Ramsey spectroscopy
M. Abdel Hafiz, C. Carlé, N. Passilly +3
The mid-term fractional frequency stability of miniaturized atomic clocks can be limited by light-shift effects. In this Letter, we demonstrate the implementation of a symmetric Au…
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…
Doppler-free spectroscopy on Cs D line with a dual-frequency laser
Moustafa Abdel Hafiz, Grégoire Coget, Emeric De Clercq +1
We report on Doppler-free laser spectroscopy in a Cs vapor cell using a dual-frequency laser system tuned on the Cs D line. Using counter-propagating beams with crossed linear…
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…
