Abstract :
Recent progress are reported on a compact cesium cell atomic frequency standard based on pulsed coherent population trapping. The Dick effect has been modelized and measured. The short term frequency stability has been improved to 3.2×10-13 τ-1/2. Important steps have been taken toward the understanding of the impact of laser power fluctuations on the mid-term stability, currently limited at 3.10-14 at 200s.
