In the proposed gravimeter, the momentum cavity is loaded with short single atomic pulses well-localized in momentum space, since the instantaneous velocity distribution is sharply peaked at any time. This is the analog of a femtosecond pulse propagating in an optical cavity. It would be interesting, however, to load the cavity with a continuous flow of free falling atoms coming from a continuous atom laser. At a fixed momentum, the contributions from different times would sum-up and interfere, exactly like in a P´erot–Fabry interferometer. This system would then constitute to our knowledge the first example of a momentum space cavity continuously loaded with a matter-wave beam.
