Abstract
Methods and apparatus for providing coherent atom population transfer using coherent laser beam pairs in which the frequency difference between the beams of a pair is swept over time. Certain examples include a Raman pulse adiabatic rapid passage sweep regimen configured to be used as a beamsplitter and combiner in conjunction with an adiabatic rapid passage mirror sweep or a standard Raman mirror pulse in a 3-pulse interferometer sequence.
