Optimization of Bragg scattering from atomic gratings for echo interferometry
We investigate the characteristics of near resonant Bragg scattering, the underlying process that produces a signal in a grating-echo atom interferometer. We explore how the density modulation produced in an atomic sample by momentum state interference and optical channeling can be optimally read out using a coherently Bragg-scattered traveling-wave electric field. When both the channeling and Bragg scattering processes are optimized, we report a 20-fold increase in scattering efficiency. Our results suggest that a quantitative understanding of the atomic confinement achievable by channeling is possible through an analysis of reflectivity spectra.
