Abstract

Super-radiant Rayleigh scattering from a Bose-Einstein condensate, driven by a single far-detuned laser beam, is strongly limited by dephasing due to inhomogeneous broadening. We demonstrate that the dephasing can be reversed applying a Bragg pulse of area pi after the first superradiant scattering, stimulating a superradiant echo and inducing a further transfer of atoms from the initial condensate to a condensate with relative momentum 2hk in the direction of the laser.
