Abstract
In a light-pulse atom interferometer, we use a tip-tilt mirror to remove the influence of the Coriolis force from Earth’s rotation and to characterize configuration space wave packets. For interferometers with a large momentum transfer and large pulse separation time, we improve the contrast by up to 350% and suppress systematic effects. We also reach what is to our knowledge the largest space-time area enclosed in any atom interferometer to date. We discuss implications for future high-performance instruments.

Precision Measurement with Cold Atoms
Published 27 February 2012
An improved mirror reduces the errors in an atom interferometer caused by Earth’s rotation and increases the time and spatial dimensions over which precision measurements can be made.
