摘要

在腔内饱和吸收体激光器的简单模型中，研究了通过iii型间歇从极限环过渡到混沌的过程。极限环是从有限幅值cw稳态出发的分支。在混沌区域内，我们还发现了几个时间周期窗。也有另一种过渡到混沌通过间歇从软激发极限环分岔从无激光状态。用庞加莱图和返回图以及功率谱来表征周期态和混沌态的性质。

Type-III Intermittency in a Simple Model of a Laser with Intracavity Absorber.

Transition from a limit cycle to chaos via type-III intermittency /1/ has been studied in a simple model of a laser with intracavity saturable absorber /2-4/. The limit cycle branches from a finite amplitude cw steady state. Within the chaotic region we have also found several time periodic windows. There is also another transition to chaos via intermittency from a softly excited limit cycle bifurcating from the no lasing state. Poincaré and return maps together with power spectra have been used to characterize the properties of the periodic and chaotic states.
