• In this letter we describe a new method of reducing one or two components of atomic velocity using an optical dipole force. The optical dipole force produces a harmonic potential transverse to the Gaussian optical beam. If the initial atomic position is close to the center of the beam, the transverse velocity component becomes almost zero after a quarter period of harmonic oscillation. If the laser is switched off at this moment, a very small transverse velocity component can be obtained. The use of a far-detuned laser reduces the heating due to spontaneous scattering and enables us to obtain a sub-photon recoil velocity component.
