摘　　要：随着激光冷却技术的发展,原子可冷却到质心运动作量子描述.自从1996年Scully等人首次研究了用超冷原子注入微波激射后,一种完全新型的诱导辐射Mazer便成了量子光学的研究热点.文章应用了“Mazer”的概念,提出了在动态Stark移动下的双光子Jaynes- Cumm ings模型.并在粒子数态、相干态下,计算了在一维方形模式函数下的发射几率.With the breakthough progress in laser cooling, atoms can be cooled to the point that their center-of-mass (CM) motion has to be described by quantum mechanics, which lead to a completely new kind of induced emission called “mazer”(microwave amplication via Z-motion-induced emission of radiation). The concept of the “mazer” was appied to two-photon Jaynes-Cummings model under the dynamic Stark shift, and calculated its emission probability in the special case of a mesa mode funtion. The studies were based not only on the case in which the cavity field is initially in a number state, but alse on the case in which the cavity field is initially in a coherent state.
