    • The invention concerns a guided coherent atom source (1) comprising means for generating neutral atoms in a gaseous state (2), means for cooling the atoms gas (3), means for generating a magnetic field (4), comprising an electro-magnetic micro-chip (6) deposited on a surface (18) of a substrate (14), and capable of condensing the atoms in a magnetic trap, means for generating an electro-magnetic RF field capable of extracting the condensed atoms, optical means (10) for emitting and directing an optical coherent beam (12) toward the condensed atoms able to guide the condensed atoms, characterized in that the optical means (10) and the electro-magnetic micro-chip (6) are integrated onto the same substrate (14). The invention also concerns an atomic interferometer using such a source.
    • 本发明涉及一种引导相干原子源(1),包括用于产生气态的中性原子的装置(2),用于冷却原子气体(3)的装置,用于产生磁场(4)的装置,包括电磁 沉积在基板(14)的表面(18)上并能够在磁捕集器中冷凝原子的微芯片(6),用于产生能够提取冷凝原子的电磁RF场的装置,光学装置 10),用于将光学相干光束(12)发射并引导到能够引导冷凝原子的凝聚原子,其特征在于,光学装置(10)和电磁微芯片(6)被集成到相同的基板 (14)。 本发明还涉及使用这种源的原子干涉仪。
