Abstract
We present transit time corrections for the diffusive decay of a ground state population grating formed by spatially periodic optical pumping. We present two classes of results, the first of which applies to a population grating with a Gaussian envelope that is probed using coherent scattering by a laser beam with a Gaussian spatial profile. The second applies to a population grating with a rectangular envelope that is probed using coherent scattering by a laser beam with a rectangular spatial profile. These corrections have been recently used to quantify systematic effects arising from the transit time in measurements of Rb-inert gas diffusion coefficients that can be applied to realize a quantum pressure sensor.Citation
