An inverted crossover resonance within one Zeeman manifold
Liam A. Salter, Emeric de Clercq, John J. McFerran
We carry out investigations of inverted crossover resonances in -driven four-level systems where can be zero. Through the use of sub-Doppler frequency modulation spectrosco…
High-performance coherent population trapping clock with polarization modulation
Peter Yun, François Tricot, Claudio Eligio Calosso +5
We demonstrate a vapor cell atomic clock prototype based on continuous-wave (CW) interrogation and double-modulation coherent population trapping (DM-CPT) technique. The DM-CPT tec…
Coherent population trapping with polarization modulation
Peter Yun, Stephane Guerandel, Emeric de Clercq
Coherent population trapping (CPT) is extensively studied for future vapor cell clocks of high frequency stability. In the constructive polarization modulation CPT scheme, a bichro…
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…
