Alain Miffre, Marion Jacquey, Matthias Büchner, Gérard Trenec, Jacques Vigue

摘要:

我们已经建立和操作的马赫-曾德尔型原子干涉仪。原子波是在氩气中接种的锂的超声束,并且用于原子波的反射镜和分束器基于在671 nm处的激光驻波上的弹性布拉格衍射。我们在这里给我们的实验装置和用于调整其组件的程序的详细描述。然后,我们提出了实验信号,表现出原子干涉效应具有非常高的可见性,高达84.5%。我们描述了一系列的实验测试的灵敏度条纹的可见性的主要对准缺陷和磁场梯度。

英文摘要:

We have built and operated an atom interferometer of the Mach-Zehnder type. The atomic wave is a supersonic beam of lithium seeded in argon and the mirrors and beam-splitters for the atomic wave are based on elastic Bragg diffraction on laser standing waves at 671 nm. We give here a detailed description of our experimental setup and of the procedures used to align its components. We then present experimental signals, exhibiting atomic interference effects with a very high visibility, up to 84.5 %. We describe a series of experiments testing the sensitivity of the fringe visibility to the main alignment defects and to the magnetic field gradient.
