| 摘 要： | 研究了三能级原子与多模光场相互作用的量子系统，从系统的密度矩阵运动方程出发讨论了无粒子数反转探测场的增益条件，发现当驱动场拉比频率取5，探测场拉比频率取1，非相干抽运取3，驱动场失谐量取3时，系统可以在偏离共振的两端获得粒子数无反转而相应的探测场获得了增益，即实现了无粒子数反转激光，其在光通信方面具有重要的应用价值。

| Abstract: | The quantum system of three-level atom interaction with multimode light fields is studied. By using the density matrix equations motion of the system, the conditions for realizing the probe fields gain without inversion in the system are discussed. When the Rabi frequency of the driving fields is 5, the Rabi frequency of the probe fields is 1, the incoherent pump is 3 and the detuning of the driving fields is 3, the gain of the probe fields without the inversion is achieved. It has very important application value in the field of optical communication. |
