Limitations of long term stability in a coherent population trapping Cs clock
Olga Kozlova, Jean-Marie Danet, Stéphane Guérandel +1
Vapor cell atomic clocks exhibit reduced frequency stability for averaging time between about one hundred and a few thousand seconds. Here we report a study on the impact of the ma…
Ramsey spectroscopy of high-contrast CPT resonances with push-pull optical pumping in Cs vapor
Xiaochi Liu, Jean-Marc Mérolla, Stéphane Guérandel +2
We report the detection of high-contrast and narrow Coherent Population Trapping (CPT) Ramsey fringes in a Cs vapor cell using a simple-architecture laser system. The latter allows…
Coherent Population Trapping Resonances in Buffer Gas-filled Cs Vapor Cells with Push-Pull Optical Pumping
Xiaochi Liu, Jean-Marc Mérolla, Stéphane Guérandel +3
We report on a theoretical study and experimental characterization of coherent population trapping (CPT) resonances in buffer gas-filled vapor cells with push-pull optical pumping…
