研究了初始处于共上能级的三能级原子与两个初始相干辐射场的相互作用,得到了原子能级算符及光子数平均值的解析近似解,给出衰变、恢复期及初振荡周期,并和计算机数值计算结果进行了比较,两者符合较好。The interaction of a three-level atom initially in the common upper state with two initially coherent fields is investigated. Approximate analytic solutions for mean atomic level occupations and photon numbers are given, which exhibit collapse, revival and initial oscillation period explicitly. These are compared with the results of numerical, calculation, they agree satifactorily.
