摘要

在复杂光学系统领域,掺铒光纤环形激光器(EDFRL)是一种必不可少的光纤激光器。该激光系统通常存在成百上千个纵向模,表现出复杂模跳变和高维混沌等非线性模动力学特性。本文对自由运行多纵模EDFRL的动态输出进行了实验研究和数值模拟。获取中心波长1546.767nm附近密集的单个纵向模组实时频率和时间强度动态的方法是基于外差检测,利用被采用激光器和参考激光器的光干涉产生被利用的拍频信号。用射频分析仪和下降图记录外差信号的频率动态和时间演变。根据实验结果,检测了MLM EDFRL输出的模态动态,并对模态强度进行了分析。为了模拟和解释实验结果,本文讨论了基于离子和离子对在增益介质中可饱和吸收的MLM激光模型,以及相应纵向模式的交叉耦合操作。MLM激光模型能有效地描述大量纵向模态的个体行为和聚类行为,在频域理论上再现了EDFRL系统的多模态动力学。

Experimental observation and numerical analysis for dynamical output in free-running multi-longitudinal mode erbium doped fiber ring laser
In the field of complex optical systems, erbium doped fiber ring laser(EDFRL) is a kind of imperative fiber laser. Hundreds and thousands of longitudinal modes can typically coexist in this laser system, exhibiting nonlinear mode dynamics such as complex mode hopping and high-dimensional chaos. In this paper, dynamical output in free-running multi-longitudinal mode(MLM) EDFRL has been investigated experimentally and simulated numerically. Method to obtain real-time frequency and temporal intensity dynamics in group of dense individual longitudinal modes around central wavelength 1546.767nm is based on heterodyne detection, the utilized beat signal is generated by optical interference of adopted laser and reference laser. Frequency dynamics and time evolutions of heterodyne signal can be recorded by a radio frequency analyzer and fall graph. According to the experimental results, the output of MLM EDFRL mode dynamics is detected and the analysis for mode intensity can be obtained. Trying to simulate and explain the experimental observations, MLM laser model based on the saturable absorption of ions and ion-pairs in the gain medium, together with cross-coupling operation of corresponding longitudinal modes, has been discussed. The MLM laser model can effectively describe the individual behavior and clustering behavior of a large number of longitudinal modes, and reproduce theoretically the multi-mode dynamics of EDFRL system in frequency domain.
