Exploding soliton in an anomalous-dispersion fiber laser

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.
