An innovative laser bench for a high performance compact cesium CPT clock

Year: 2023

Type: conference-paper

Abstract: We developed and implemented a miniature electro-optical bench for the stabilization of a dual-frequency laser beam for high-contrast CPT interrogation of cesium. Preliminary results of optical intensity and wavelength simultaneous stabilizations give respective noise reduction of 15 dB and 60 dB at low frequencies. These performances are in line with targeted clock stability of 5×10-13 at 1 s. For longer time scales, a study of the optical power stability shows a drastic reduction of power fluctuations and highlights the temperature sensitivity of the optical components.
