Light-pulse atom interferometry has become a formidable tool for high precision
applications in quantum sensing and tests of fundamental physics. Nowadays
interferometers of this type rely on either Bragg or Raman diffraction.
Retro-reflective setups with two counter-propagating lattices reduce the effect of
wave-front distortions and mirror vibrations. However, this advantage comes at
the cost of a light-shift contribution to the interferometer phase due to
off-resonant transitions. In Raman diffraction the impact of light-shifts is
well understood.[1,2] For Bragg diffraction we have recently made
significant progress and demonstrated that this intrinsic effect of
beam splitters can be suppressed to a large extend by appropriately chosen pulse
envelopes.[3] In our contribution we investigate mitigation strategies as
well as different interferometer geometries.
