    Abstract

    A ground-state coherence grating involving the magnetic sublevels of the F = 3 ground state in 85Rb is created in Doppler-broadened vapor using an excitation pulse that consists of two traveling waves with orthogonally polarized wave vectors along k1 and k2. The decay of the grating due to thermal motion is probed by a traveling wave readout pulse along k2. This results in scattered signal along k1 magnetic grating free-induction decay (MGFID) that is detected using a heterodyne technique. A second excitation pulse is delayed by T with respect to the first results in a rephased grating at t = 2T magnetic grating echo (MGE). These signals disappear for small buffer-gas pressures due to velocity-changing collisions.
