A Laboratory Atom Interferometer Instrument

Nourshargh, Rustin

We have demonstrated a laboratory based, high bandwidth atom interferometer instrument and have performed an incipient gravity measurement with a fractional statistical uncertainty of ag/g = 4.4 x 10^-6 where g is the acceleration due to gravity. We have designed, constructed, and optimised numerous laser systems for this purpose, most notably a powerful Raman laser (12 W at 780 nm) which will allow large momentum transfer and large detuning interferometry to be carried out at high bandwidth for the first time. This experiment is a general purpose test bed for exploring the fundamental limitations of atom interferometer techniques.
