摘要：

We describe a new sub-Doppler cooling scheme that cools atoms to nonzero velocity vr. The atomic motion in a combined optical standing wave and constant magnetic field induces a velocity-selective magnetic resonance that produces strong cooling for negative laser detuning to vr=Z/2k, with Z the Larmor frequency. In a one-dimensinal optical molasses transverse to a thermal Rb beam we observe the bunching of the atoms into two peaks corresponding to ±vr. We present a quantitative comparison between our theory and experiment and suggest some applications. © 1990 The American Physical Society.
