摘　　要：提出了一二能级原子的Ｋ光子（Ｋ≥３）泵溥过程的Ｄｒｅｓｓｅｄ变换方法，并研究了其振荧光现象着重讨论了三光子泵浦情形，发现其Ｄｒｅｓｓｅｄ变换式与单光子和双光子泵浦情形比较呈现出规律性，其共振荧光仍为三峰结构，但Ｄｒｅｓｓｅｄ原子的双光子荧光跃迁速率是其单光子荧光跃迁速率的四倍．A dressed transformation is proposd to treat the processes by K-photon(K≥3)pumpinga two-level atom,and its resonance fluorescence is investigated The three-photon dressed pumped process-es is discussed emphaticallyWe find that the three-photon that of one or two-photon. The spectrum of re-somance fluorescence also consists of three peaks, but the two-photon fluorescence transition rate of themree-photon dressed atom is four times as that of its one-photon.
