Improvement of Fluorescence Amplification Circuit Module for Optically Pumped Cesium Beam Atomic Clock

We propose a circuit module for amplifying the fluorescence signal which has been collected in the detector, and we can use this module to remove the environment perturbation imposed on the atomic clock and eventually it could improve the stability of the atomic clock. We have detailed the scheme of the circuit module and then we described the function of each part. We measure the frequency stability of our engineering model, the optically pumped cesium beam atomic clock, equipped with this circuit module, and the experiment result of this engineering model is comparable with the 5071A(Standard).
