Interference of an array of atom lasers
We report on the observation of interference of a series of atom lasers. A comb-like array of atomic beams is generated by outcoupling atoms from distinct Bose-Einstein condensates confined in the different sites of a mesoscopic optical lattice. The observed interference signal arises from the spatial beating of the overlapped atom laser beams, which is monitored over a range corresponding to 2\,ms of free fall time. The relative de Broglie frequencies and phases of the atom lasers were measured. © 2008 The American Physical Society.
