In order to diffract atoms from an evanescent light reflection grating the Rabi frequency must be greater than the Doppler shift associated with the atomic velocity. For thermal atoms this cannot be achieved using dye lasers. Rather than slow the atoms we have produced a moving light grating and observe resonances in the reflectivity of the grating for certain grating velocities. The position of these resonances fulfils the Doppleron condition Δ’=nΔ D ’, which is consistent with a dressed state model for diffraction from such a grating.
