Taking advantage of technology of spatio-temporal reconstruction and dispersive Fourier transform (DFT), we experimentally observed the buildup dynamics of dissipative soliton in an ultrafast fiber laser in the net-normal dispersion regime. The soliton buildup dynamics were analyzed in both the spectral and temporal domains. We firstly revealed that the appearing of the spectral sharp peaks with oscillation structures during the mode-locking transition is caused by the formation of structural dissipative soliton. The experimental results were explained by the numerical simulations. These findings would give some new insights into the dissipative soliton buildup dynamics in ultrafast fiber lasers.
利用时空重构技术和色散傅里叶变换（DFT），我们在实验中观察了净正常色散区域超快光纤激光器中耗散孤子的形成动力学。在光谱和时域中对孤子形成动力学进行了分析。我们首先揭示了锁模转变期间具有振荡结构的光谱尖峰的出现是由结构耗散孤子的形成引起的。通过数值模拟对实验结果进行了解释。这些发现将为超快光纤激光器中耗散孤子的形成动力学提供一些新的见解。
