ANALYTIC SOLUTIONS FOR COHERENT THREE-LEVEL J-C MODEL
相干三能级J—C模型的解析解

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.
