The evolutions of conventional soliton (CS) and breathing soliton (BS) dynamics in an anomalous dispersion Er-doped fiber laser are investigated experimentally and numerically. Based on the dispersive Fourier transform technique, the evolution processes of CS buildup and extinction are observed and discussed. It was found that a transitional unstable stage exists during the buildup and extinction process. In the same laser, BS state is also reached. Simulation results of CS and BS evolutionary dynamics are anastomotic with experimental results. The results may contribute to better understanding of the complex pulse dynamics in ultrafast fiber lasers.

反常色散光纤激光器中常规孤子和呼吸孤子的时空动力学

通过实验和数值研究了反常色散掺铒光纤激光器中常规孤子 (CS) 和呼吸孤子 (BS) 动力学的演变。基于色散傅里叶变换技术，观察和讨论了CS的建立和消亡的演化过程。发现在建立和消亡过程中存在一个过渡不稳定阶段。在同一激光器中，也达到了 BS 状态。CS和BS进化动力学的模拟结果与实验结果吻合。结果可能有助于更好地理解超快光纤激光器中的复杂脉冲动力学。
