Autor: Vincent Maurice, Clément Carlé, Shervin Keshavarzi, Ravinder Chutani, Samuel Queste, Ludovic Gauthier-Manuel, Jean-Marc Cote, Rémy Vicarini, Moustafa Abdel Hafiz, Rodolphe Boudot, Nicolas Passilly
Publikováno v: Microsystems & Nanoengineering, Vol 8, Iss 1, Pp 1-11 (2022)
Abstract 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 purity and accuracy. Glass-blowing techniques and craftsmanship

High-contrast sub-Doppler absorption spikes in a hot atomic vapor cell exposed to a dual-frequency laser field
Autor: Moustafa Abdel Hafiz, Denis Brazhnikov, Grégoire Coget, Alexei Taichenachev, Valeriy Yudin, Emeric de Clercq, Rodolphe Boudot
Publikováno v: New Journal of Physics, Vol 19, Iss 7, p 073028 (2017)
The saturated absorption technique is an elegant method widely used in atomic and molecular physics for high-resolution spectroscopy, laser frequency standards and metrology purposes. We have recently discovered that a saturated absorption scheme wit

Cs microcell optical reference with frequency stability in the low 10−13 range at 1 s
Autor: Anthony Gusching, Jacques Millo, Ivan Ryger, Remy Vicarini, Moustafa Abdel Hafiz, Nicolas Passilly, Rodolphe Boudot
Publikováno v: Optics Letters. 48:1526
We describe a high-performance optical frequency reference based on dual-frequency sub-Doppler spectroscopy (DFSDS) using a Cs vapor microfabricated cell and an external-cavity diode laser at 895 nm. Measured against a reference optical signal extrac

Two-frequency sub-Doppler spectroscopy of the caesium D1 line in various configurations of counterpropagating laser beams
Autor: D. V. Brazhnikov, S. M. Ignatovich, I. S. Mesenzova, Rodolphe Boudot, A. M. Mikhailov, Mikhail N Skvortsov
Publikováno v: Quantum Electronics. 50:1015-1022
Sub-Doppler resonances in caesium vapours are studied in a laser field produced by counterpropagating two-frequency light beams with mutually orthogonal linear polarisations. The beams are in resonance with optical transitions in the D1 line, the fre

Pulsed-CPT Cs-Ne microcell atomic clock with frequency stability below 2 × 10−12 at 105 s
Autor: Clément Carlé, Moustafa Abdel Hafiz, Shervin Keshavarzi, Rémy Vicarini, Nicolas Passilly, Rodolphe Boudot
Publikováno v: Optics Express. 31:8160
We report on the mid-term stability progress of a table-top coherent population trapping (CPT) microcell atomic clock, previously limited by light-shift effects and variations of the cell's inner atmosphere. The light-shift contribution is now mitiga

Phase noise mitigation of the microwave-to-photonic conversion process using feedback on the laser current
Autor: Damien Teyssieux, Rodolphe Boudot, Christophe Fluhr, Jacques Millo
Publikováno v: Journal of the Optical Society of America B. 39:3108
The generation and transfer of ultra-stable microwave signals are of paramount importance in numerous applications spanning from radar systems to communications and metrology. We demonstrate residual phase noise mitigation at 10 GHz of a directly mod

Journal of Physics: Conference Series (JPCS), 2021, 1859, pp.012019. ⟨10.1088/1742-6596/1859/1/012019⟩
We review three laser spectroscopy schemes developed recently for observation of high-contrast enhanced-absorption nonlinear resonances in small alkali-vapor cells. In our experiments, optical transitions within the cesium D1 line are involved and a
