激光冷却原子新机制

New Mechanisms for Laser Cooling of Atoms

本文综述了激光冷却原子的研究新进展，着重从物理图象上介绍了偏振梯度冷却、磁感应冷却和速度选择相干粒子数捕陷等新机制．文中还将新的冷却机制和传统冷却机制进行了对比．

We summarize the latest developments in laser cooling, with emphasis on the physical principles underlying polarization gradient cooling, magnetic field induced cooling and velocity-selective coherent population trapping. The new mechanisms are compared with the traditional one.
