Ramsey CPT Signal Generation with a Miniature Clock Bench and a Dual-Frequency Optical Generator

Year: 2023

Type: conference-paper

Abstract: We demonstrate, for the first time, Ramsey CPT spectroscopy with a miniature electro-optical bench associated to a dual-frequency generator based on combined optical injection locking and optical phase locking techniques Preliminary results show Ramsey CPT resonance with a contrast of 2% at the Cesium D2 line. Frequency difference locking loops lead to a contribution of Dick effect to fractional frequency stability lower than 1.7x10-13 at 1 s, in line with targeted clock stability of 5×10-13 at 1 s.
