Title (EN) ARCHITECTURE FOR COMPACT COLD ATOM CLOCKS
(FR) ARCHITECTURE POUR HORLOGES À ATOMES FROIDS COMPACTES
Abstract:
(EN) An atomic oscillator device includes an atomic oscillator, a controlled oscillator, a resonance controller, and a cold-atom clock output. The atomic oscillator comprises a two-dimensional optical cooling region (2D OCR) for providing a source of atoms and a three-dimensional optical cooling region (3D OCR) for cooling and/or trapping the atoms emitted by the 2D OCR. The atomic oscillator comprises a microwave cavity surrounding the 3D OCR for exciting an atomic resonance. The controlled oscillator produces an output frequency. The resonance controller is for steering the output frequency of the controlled oscillator based on the output frequency and the atomic resonance as measured using an atomic resonance measurement. The cold-atom clock output is configured as being the output frequency of the controlled oscillator.
(FR) L'invention concerne un dispositif à oscillateur atomique comprenant un oscillateur atomique, un oscillateur commandé, un dispositif de commande de résonance et une sortie d'horloge à atomes froids. L'oscillateur atomique comprend une région de refroidissement optique bidimensionnelle (OCR 2D) pour fournir une source d'atomes et une région de refroidissement optique tridimensionnelle (OCR 3D) pour refroidir et/ou piéger les atomes émis par l'OCR 2D. L'oscillateur atomique comprend une cavité micro-onde entourant l'OCR 3D pour exciter une résonance atomique. L'oscillateur commandé produit une fréquence de sortie. Le dispositif de commande de résonance est destiné à diriger la fréquence de sortie de l'oscillateur commandé sur la base de la fréquence de sortie et de la résonance atomique telle que mesurée par une mesure de résonance atomique. La sortie d'horloge à atomes froids est conçue comme étant la fréquence de sortie de l'oscillateur commandé.
