摘要

研究了6Li原子在双色激光场中在D2和D1线上激发跃迁的动力学。该模型考虑了6Li能级的复杂实结构（包括塞曼简并）以及激光场的非均匀空间偏振。发现6Li原子的共振D2线的光场分量的失谐和偏振配置对于激光冷却具有根本的重要性。证明了原子冷却到多普勒极限以下的可能性。

Laser Cooling of Lithium-6 Atoms in a Bichromatic Light Field

The kinetics of ⁶Li atoms in a bichromatic laser field exciting transitions on D2 and D1 lines is investigated. The model takes into account the complex real structure of energy levels of ⁶Li (including the Zeeman degeneracy) as well as the nonuniform spatial polarization of the laser field. It is found that detuning and the polarization configuration of the light field component of the resonant D2 line of the ⁶Li atom are of fundamental importance for laser cooling. The possibility of cooling of atoms below the Doppler limit is demonstrated.
