Abstract
This paper presents the results of studies into the spatial behaviour of the gradient force acting on a three-level Lambda -atom in a two-frequency standing light wave. The effect of spatially inhomogeneous optical pumping and light-induced level shifts results in the wavelength-averaged force becoming other than zero. The magnitude of the rectified force is comparable with that of the gradient force in a single-frequency standing light wave.Keywords
