High Data Rate Atom Interferometric Device

Technology Area

A light-pulse atomic interferometry (LPAI) apparatus is provided.  The LPAI apparatus comprises a vessel, two sets of magnetic coils configured to magnetically confine an atomic vapor in two respective magneto-optical traps (MOTs) within the vessel when activated, and an optical system configured to irradiate the atomic vapor within the vessel with laser radiation that, when suitably tuned, can launch atoms previously confined in each of the MOTs toward the other MOT.  In embodiments, the magnetic coils are configured to produce a magnetic field that is non-zero at the midpoint between the traps.  In embodiments, the time-of-flight of the launched atoms from one MOT to the other is 12 ms or less.  In embodiments, the MOTs are situated approximately 36 mm apart.  In embodiments, the apparatus is configured to activate the magnetic coils according to a particular temporal magnetic field gradient profile.
