研究了光反馈作用下单模激光在延时时间远小于弛豫振荡周期的极限条件下的动力学行为。使用集成的DFB设备使我们能够控制反馈阶段。该系统显示出非常丰富的非线性现象。其中有两种与不同频率的正则自脉动相关的Hopf分岔，以及一种折叠分岔和一种倍周期分岔。
The dynamical behavior of a single-mode laser subject to optical feedback is investigated in the limit, when the delay time is much shorter than the period of the relaxation oscillations. Use of an integrated DFB device allows us to control the feedback phase. The system shows a very rich manifold of nonlinear phenomena. Among them are two kinds of Hopf bifurcations associated with regular self-pulsations of different frequencies as well as a fold and period doubling bifurcation.
