There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 1970s. The estimated fractional frequency uncertainty of today's leading

International audience; Nous présentons en premier lieu des travaux visant au développement d’horloges atomiques microondes à microcellule de haute stabilité, basées sur le phénomène de piégeage cohérent de population (CPT). Nous démontro

We report the implementation of a CPT-based Cs cell microwave feedback oscillator. Here, a high-Q atomic resonance initiated through CPT in a buffer-gas filled Cs vapor cell is detected with a fast photodiode, amplified and sustained in a loop oscill

We present an in-progress study about the development of a microcell atomic clock based on coherent population trapping (CPT). In a recent study, we demonstrated significant lightshift mitigation with the implementation of a symmetric auto-balanced R

International audience; We investigate the use of pulsed Ramsey-CPT spectroscopy in a coherent population trapping (CPT) atomic clock using a microfabricated buffer gas-filled Cs vapor cell. Tests are performed on a table-top setup with an external a
