Coherent dynamics of a single two-level atom in laser field: hyperfine structure case
超精细结构对激光与二能级原子相互作用的影响

The influence of the atomic hyperfine structure on the dynamics of a single two-level atom in laser field has been studied in this paper. A simplified model was built up. With this model, some calculations were carried out. We draw a conclusion that there exists an optimal laser frequency when the maximal average probability on the upper energy level is required. The laser intensity has little influence on the probability that the atom stays on a certain energy level.
