摘　　要：报道了利用红移漫射光冷却原子的新机制。理论计算了二能级原子在这一光场中所受的辐射压力，在实验上观测到了钠原子束在负失谐漫射光中的减速。A new deceleration and cooling mechanism by red shifted diffuse light have been reported. The expression of radiation pressures produced by monochromatic red shifted diffuse light are obtained by solving the two-level atom model and deceleration of Na atoms in an atomic beam have been observed in experiment.
