Atom interferometers in optical cavities benefit from strong laserintensities and high-quality wavefronts. The laser frequency pairs that areneeded for driving Raman transitions (often generated by phase modulating amonochromatic beam) form multiple standing waves in the cavity, resulting in aperiodic spatial variation of the properties of the atom-light interactionalong the cavity axis. Here, we model this spatial dependence and calculatetwo-photon Rabi frequencies and ac Stark shifts. We compare the model tomeasurements performed with varying cavity and pulse parameters such as cavityoffset from the carrier frequency and the longitudinal position of the atomcloud. We show how setting cavity parameters to optimal values can increase theRaman transition efficiency at all positions in the cavity and nearly doublethe contrast in a Mach-Zehnder cavity atom interferometer in comparison to theunoptimized case.
