摘　　要：本文讨论了光与四能级原子的相干作用，其解析结果表明：为了有效地电离原子，第二束光强应远大于第一、第三束光强。比例因子α＝０．１。The coherent interaction between lights and a four-level atom was resolved exactly in this paper. The analytic results showed that in order to have a higher ionization probability of an atom, the intensity of the second light must be muCh greater than that of the first and the third. The ratio factor α= 0.1.
