In chapter 4, laser cooling and trapping and applications of ultracold atoms are reviewed.The beam and atom interaction theory is analyzed. 第四章針對空心光束的應用，綜述了激光與原子相互作用的物理機制，分析了空心光束冷卻原子的機理以及研究動(dòng)態(tài)。
In this paper,their interaction between the two-level atomic quantized translational motion and internal state population in a quantized standing-wave cavity are studied. 討論了在駐波腔場(chǎng)中兩能級原子的量子化平移運動(dòng)與原子內態(tài)布居間的相互影響。
