| 摘 要： | 激光偏振梯度致冷是另外一种使中性原子降温的有效方法，而且能使原子温度突破多普勒温度极限。实验上首先由W．D．Phillips领导的研究小组于1988年采用并获得成功，然后Dalibard和Cohen-Tannoudji给予了理论解释。激光偏振梯度致冷原理大致描述如下： |
| 关 键 词： | 激光致冷 中性原子 激光偏振 有效方法 致冷原理 理论解释 多普勒 梯度 温度 |

| Abstract: | An introduction is given in the simple terms for anti-Stokes cooling used for solids, and the cooling schemes used for neutral atoms, for example, Doppler cooling, evaporation cooling, polarization gradient cooling, cooling based on velocity-selective coherent population trapping and cavity cooling. It contains the relevant principles, technology, present development and applications. |
| Keywords: | anti-Stokes cooling Doppler cooling evaporation cooling polarization gradient cool-ing velocity-selective coherent population trapping cooling cavity cooling |
