Towards a high-stability Cs-microcell stabilized laser with dual-frequency sub-Doppler spectroscopy

Year: 2023

Type: conference-paper

Abstract: We report on the frequency stabilization of an external-cavity diode laser onto a Cs micro-fabricated cell using dual-frequency sub-Doppler spectroscopy (DFSDS). The Allan deviation of the laser, measured by creating a beat-note signal with an ultra-stable 895 nm signal extracted from a frequency comb phase locked to a cavity-stabilized laser, is 3x10-13 at 1 s and below 5x10-14 at 100 s. The stability level at 1 s is currently limited by the intermodulation effect due to the frequency noise (FM noise) of the laser. Studies are in progress to identify main limitations to the laser mid-term stability.
