Abstract :
Recent progress are reported on a compact cesium cell atomic frequency standard based on pulsed Coherent Population Trapping interaction in the Dicke regime. Main short term and long term limiting parameters have been identified. Last improvements have permitted to reach a stability of 7×10-13 at 1sec and 2×10-14 at 2000 s. The noise characterization process is presented in this article.
