The formation and breaking dynamics of dissipative solitons (DSs) are observed in a passive mode-locked fiber laser using dispersive Fourier transform technique. Q-switched instabilities are observed both in the formation of DS and the transition breaking dynamics of DSs on gradually increasing the pump power. The real time temporal and spectral dynamics of the entire dynamics are discussed. The generation of the Q-switched instabilities could be attributed to the weak pulse energy before reaching the stable soliton state. These findings would facilitate an in-depth understanding of the formation and breaking dynamics of DSs.

锁模光纤激光器中耗散孤子形成和断裂动力学的实时观察

使用色散傅里叶变换技术在无源锁模光纤激光器中观察到了耗散孤子（DSs）的形成和破坏动力学。在DS的形成和DSs在逐渐增加泵浦功率时的过渡破坏动力学中都观察到Q转换的不稳定性。讨论了整个动力学的​​实时时间和光谱动力学。Q开关不稳定性的产生可能归因于在达到稳定孤子状态之前的弱脉冲能量。这些发现将有助于深入了解DS的形成和破坏动力学。
