Raman-Ramsey interference has proved a very effective technique to implement compact and high performing vapor cell frequency standards. In this paper, we theoretically characterize Raman-Ramsey resonances in an optically thick atomic vapor. Specifically, some parameters of interest for frequency standards...
A Raman-RamseyCscell atomic clock based on Coherent Population Trapping is studied. High contrasts and narrow width Ramsey fringes are achieved by combining an original double-lambda scheme and a pulsed interrogation technique. The pulsed method allows a strong reduction of the light shift effect ...

Here, we propose a method to reduce the EIT spectral linewidth using a Ramsey interrogation approach, allowing multiple interrogations of atomic coherence, using either temporally or spatially separated laser beams. Our theoretical calculations predict that the linewidth of such Raman-Ramsey spectral ...
We performed the Ramsey experiment of optical separated oscillatory fields based on a cold continuous ~(87)Rb atomic beam. The beam had a free evolution time of 3.4 ms over a short interaction-zone separation of 42 mm, producing a central Raman-Ramsey fringe with a linewidth of 146 Hz (...
