摘　　要：Recently more attention has been paid to the study of lasing without population inver-sion. It has been found that many schemes, with the help of optical coherence or quantuminterference effect, may establish such optical phenomenon as that in refs. [1-7]. In thoselaser models, in order to have the optical gain on the corresponding transition a coherentpump is required to drive the systems, and additional pumps, coherent or incoherent,
