Abstract

L'invention concerne un système d'interféromètre atomique comprenant une source d'atomes générant une bouffée d'atomes froids (60), une source laser générant une séquence d'impulsions lumineuses (14) et un système de détection configuré pour mesurer un déphasage interférométrique de ladite bouffée d'atomes froids (60). Selon l'invention, le système comporte une cavité optique résonante (100) comprenant un système optique intra-cavité (20, 21, 22), la cavité optique résonante (100) recevant une impulsion lumineuse de ladite séquence et générant un mode transverse de résonance ayant une première taille (w1) dans une première partie (81) de la cavité (100, 101), et, le système optique intra-cavité (20, 21, 22) étant configuré pour agrandir ledit mode transverse de résonance à une deuxième taille (w2) dans une deuxième partie (82) de la cavité optique résonante (100) et ladite bouffée d'atomes froids (60) étant superposée spatialement et temporellement avec ledit mode transverse de résonance dans la deuxième partie (82) de la cavité optique résonante (100).An atomic interferometer system includes a source of atoms generating a puff of cold atoms (60), a laser source generating a sequence of light pulses (14) and a detection system configured to measure a phase shift. interferometric of said puff of cold atoms (60). According to the invention, the system comprises a resonant optical cavity (100) comprising an intra-cavity optical system (20, 21, 22), the resonant optical cavity (100) receiving a light pulse of said sequence and generating a transverse mode of resonance having a first size (w1) in a first part (81) of the cavity (100, 101), and, the intra-cavity optical system (20, 21, 22) being configured to enlarge said transverse mode of resonance to a second size (w2) in a second part (82) of the resonant optical cavity (100) and said puff of cold atoms (60) being spatially and temporally superimposed with said transverse mode of resonance in the second part (82) of the resonant optical cavity (100).
