Abstract

Dual-frequency sub-Doppler spectroscopy (DF SDS) in vapor cells allows the detection of enhanced-absorption natural-line-width resonances.We investigate here the application of this spectroscopy technique into a Cs micro-fabricated cell. The dependence of the sub-Doppler resonance on the laser intensity is described. The influence of the cell temperature and the retroreflection mirror position was also studied. A preliminary laser beat-note between two 894 nm lasers, each stabilized using DF SDS, demonstrates an Allan deviation lower than 2 × 10-12 at 1 s and at the level of 10-12 at 102. Main contributions to the short-term and mid-term stability budget are under study. Latest results will be reported at the conference.
