摘要

摘要考虑到原子级的实际结构，建立了一个在多色场中激光冷却碱原子的模型。该模型以 6Li 原子为例进行了测试。研究了不同偏振光场成分下激光冷却轻碱原子可达到的最低温度，并证明了冷却温度低于多普勒极限的可能性。

Limits of Laser Cooling of Light Alkali Metals in a Polychromatic Light Field

A model was developed for laser cooling of alkali atoms in a polychromatic field, considering the real structure of atomic levels. The model was tested by the example of the ⁶Li atom. The minimum achievable temperatures of laser cooling of light alkali atoms were studied for different polarizations of the light field components, and the possibility of cooling below the Doppler limit was shown.
