In this Letter, we report an experimental observation of coherent soliton explosions in an anomalous-dispersion fiber laser. Specifically, by taking advantage of dispersive Fourier transformation method, some remarkable spectral signatures of soliton explosions in anomalous-dispersion regime are highlighted, such as the spectral collapse, destruction of Kelly sidebands, and transient soliton molecules. Our results give new insights into the soliton explosions dynamics in ultrafast fiber lasers.

异常色散光纤激光器中的孤子爆炸

在这封信中，我们报告了在异常色散光纤激光器中相干孤子爆炸的实验观察。具体而言，利用色散傅里叶变换方法，突出了反常色散状态下孤子爆炸的一些显着光谱特征，例如光谱崩溃，凯利边带破坏和瞬态孤子分子。我们的结果为超快光纤激光器中的孤子爆炸动力学提供了新的见解。
