We introduce a general wave-packet isotope-separation scheme exploiting the optical Ramsey method. Optically excited molecular wave packets in different isotopes develop a well-defined phase difference after just a few vibrational periods. Phase-locked pairs of optical pulses are able to selectively pump one isotope back down to the ground state and enhance the excited-state population of the other isotope. The method is illustrated by simulating wave-packet isotope separation of a mixture of Br-79(2), Br-81(2), and (BrBr)-Br-79-Br-81. We also exploit phase-locked pairs of optical pulses to reduce the time required for the spatial separation of wave packets.
