摘　　要：利用开放的 V型系统密度矩阵运动方程组的零级稳态解 ,从定性分析和数值计算两个方面讨论了导致无反转激光的途径。研究结果表明 :系统可以通 pitchfork分岔和 Hopf分岔两种失稳机制产生无反转激光 ;激光腔损失、非饱和激光跃迁增益、原子退出速率和注入速率的变化对无反转激光的产生有明显的影响。The way resulting in the lasing without inversion is discussed from the both respects the qualitative analysis and numerical calculation by using the zero order stationary solution of the density matrix motion equations of the open V type system.The study shows that:the lasing without inversion can be produced by two destabilization mechanism the pitchfork and Hopf bifurcation;the variations of the loss of laser cavity,unsaturated gain of the lasing transition,atomic exit rate and ratio of the atomic injection rates have obviously effects on the production of the lasing without inversion.
