Abstract: We report on the observation of interference of a series of atom lasers. A comblike 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 $2\phantom{\rule{0.3em}{0ex}}\mathrm{ms}$ of freefall time. The relative de Broglie frequencies and phases of the atom lasers were measured.
