Contributing to TAI with a Secondary Representation of the SI Second
Jocelyne Guéna, Michel Abgrall, André Clairon +1
We report the first contribution to the international atomic time (TAI) based on a secondary representation of the SI second. This work is done with the LNE-SYRTE FO2-Rb fountain f…
Lasers for coherent optical satellite links with large dynamics
Nicola Chiodo, Khelifa Djerroud, Ouali Acef +2
We present the experimental realization of a laser system for ground to satellite optical Doppler ranging at the atmospheric turbulence limit. Such a system needs to display good f…
Improved tests of Local Position Invariance using 87Rb and 133Cs fountains
Jocelyne Guéna, Michel Abgrall, Daniele Rovera +5
We report tests of local position invariance based on measurements of the ratio of the ground state hyperfine frequencies of 133Cs and 87Rb in laser-cooled atomic fountain clocks.…
Progress in Atomic Fountains at LNE-SYRTE
Jocelyne Guéna, Michel Abgrall, Daniele Rovera +10
We give an overview of the work done with the Laboratoire National de Métrologie et d'Essais-Systèmes de Référence Temps-Espace (LNE-SYRTE) fountain ensemble during the last five y…
Evaluation of Doppler Shifts to Improve the Accuracy of Primary Atomic Fountain Clocks
Jocelyne Guéna, Ruoxin Li, Kurt Gibble +2
We demonstrate agreement between measurements and ab initio calculations of the frequency shifts caused by distributed cavity phase variations in the microwave cavity of a primary…
An agile laser with ultra-low frequency noise and high sweep linearity
Haifeng Jiang, Fabien Kefelian, Pierre Lemonde +2
We report on a fiber-stabilized agile laser with ultra-low frequency noise. The frequency noise power spectral density is comparable to that of an ultra-stable cavity stabilized la…
