Lattice-depth measurement using continuous grating atom diffraction

10 Mar 2019 Beswick Benjamin T. Hughes Ifan G. Gardiner Simon A.

We propose a new approach to characterizing the depths of optical lattices, in which an atomic gas is given a finite initial momentum, which leads to high amplitude oscillations in the zeroth diffraction order which are robust to finite-temperature effects. We present a simplified model yielding an analytic formula describing such oscillations for a gas assumed to be at zero temperature... (read more)
