The velocity distribution of ultracold atoms passing through a resonant microwave cavity can narrow by more than an order of magnitude. This velocity selection is due to resonances in the transmission through dressed-state potentials. The proposed device is an atom-optical analog of a Fabry-Pérot resonator and allows for macroscopic coherence lengths.
