Abstract
Light Pulse Atom lnterferometryLight Pulse Atom Interferometers (LPAI) utilize Raman or Bragg transitions to coherently split, redirect, and recombine atomic wave packets.1In free space LPAIs, light pulses impart momentum kicks to freely expanding cold atomic clouds released from rest.During the atom-light interaction, the laser phase is imprinted onto the atom's wave function.Atoms experience different phase shifts along each interferometer arm which gives us information about their spatial trajectories and thus their local acceleration.The quadratic dependence of the phase shift on the interrogation time, T, have prompted researchers to increase the system's size.For field use, however, smaller compact devices are desired.Guided atom interferometers confine atoms spatially, increasing the interrogation time while minimizing the laser power needed to drive these systems.
