| 摘 要： | 建立了单模环腔CO_2激光器的数学物理模型。线性稳定性分析的结果表明,当Kerr介质的Debye弛豫速率远远大于激光工作原子的纵向弛豫速率时,系统将在低光强区出现动力学不稳定性。数值计算的结果表明,在恒定泵浦下,激光输出为一系列脉冲,基本上追随倍周期分岔的道路通向混沌。

| Abstract: | The physical and mathematical model of a ring caviy monomode CO2 laser is set up. The results of linearized stability analysis show that the dynamic instability on the region of low output intensity will appear only when the Debye relaxation rate exceeds greatly the longitudinal relaxation rate of atoms. The numerical calculation of time-dependent solutions reveals the periodic, period-doubling and chaotic behaviour. |
