摘　　要：The typically tiny effect of radiation damping on a moving body can be amplified to a favorable extent by exploiting the sharp reflectivity slope at one edge of an optically induced stop-band in atoms loaded into an optical lattice.In this paper,this phenomenon is demonstrated for the periodically trapped and coherently driven cold 87Rb atoms,where radiation damping might be much larger than that anticipated in previous proposals and become comparable with radiation pressure.Such an enhancement could be observed even at speeds of only a few meters per second with less than 1.0%absorption,making radiation damping experimentally accessible.
