Ramsey CPT Signal Generation with a Miniature Clock Bench and a Dual-Frequency Optical Generator
Stéphane Guérandel, Jérémie Cotxet, François Gutty +4
We demonstrate, for the first time, Ramsey CPT spectroscopy with a miniature electro-optical bench associated to a dual-frequency generator based on combined optical injection lock…

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…
