Hopf-type bifurcation dynamics, a universal phenomenon existing in numerous physical systems, has recently been observed in mode-locked erbium-doped fiber lasers with anomalous or normal net dispersion. This study demonstrates the real-time experimental observation of double-Hopf-type breathers in an all-normal dispersion all-polarization maintaining ytterbium-doped fiber laser instead. It is shown that the breather frequency can be modulated periodically by the additional oscillation with increasing amplitude in response to increased pump power until a stationary dissipative soliton is formed. The possible explanation of the observed double-Hopf-like bifurcation dynamics is discussed by exploring the numerical approach that combines the interplay of the population inversion in the laser medium with the pulses energy. The results provide additional building blocks for further understanding laser physics and can help in optimizing fiber cavity designs.

超快全保偏光纤激光器中双 Hopf 分岔的实时观测

Hopf 型分岔动力学是许多物理系统中普遍存在的现象,最近在具有反常或正常净色散的锁模掺铒光纤激光器中观察到。这项研究证明了双Hopf型呼吸器在全正常色散全偏振保持掺镱光纤激光器中的实时实验观察。结果表明,呼吸器频率可以通过响应于增加的泵浦功率而增加幅度的附加振荡来周期性地调制,直到形成稳定的耗散孤子。通过探索将激光介质中的布居反转与脉冲能量的相互作用相结合的数值方法,讨论了观察到的类双 Hopf 分岔动力学的可能解释。
