Abstract

L'invention concerne un procédé et un appareil permettant de fabriquer des horloges atomiques ou des magnétomètres atomiques en tant que systèmes laser auto-modulés sur la base de la physique du pompage optique en mode push-pull. Il est nécessaire qu'une cellule de vapeur atomique soit dans la cavité laser. Dans des conditions appropriées, le pompage optique en mode push-pull spontané peut survenir à l'intérieur de la cavité laser, ce qui provoque la modulation du faisceau laser à une fréquence de résonance hyperfine. A l'aide d'un photodétecteur rapide, on peut convertir le signal laser modulé en signal électrique, qui fait office de signal d'horloge atomique ou de signal de magnétomètre. Le système laser auto-modulé n'utilise aucun oscillateur local ni le circuit hyperfréquence pour verrouiller la fréquence d'oscillateur à la fréquence de résonance hyperfine et, en conséquence, consomme moins d'énergie, devenant ainsi plus compact que les systèmes classiques. Les applications de mesure du temps et de mesure de champs magnétiques en tireront profit.
