A new method for building an atomic matter-wave interferometry
原子束多光束干涉实验的一种方法

A new method for building an atomic matter wave interferometry is proposed. In this paper, a Fresnel zone plate is used for restricting the linewidth of atomic beams, then a quasi monochromatic atomic beam is obtained to illuminate four slits on a copper coil. The phenomenon of atomic interference and holograph can be observed,which is used to measure the coherent length of atomic beams.
