Real-time spectroscopy access to ultrafast fiber lasers opens new opportunities for exploring
complex soliton interaction dynamics. Here, we have reported the first observation, to the …

Solitons are stable localized wave packets that can propagate long distance in dispersive
media without changing their shapes. As particle-like nonlinear localized waves, solitons …

Over a decade ago, an analogy was drawn between the generation of large ocean waves
and the propagation of light fields in optical fibres. This analogy drove numerous …

Harmonic mode‐locking (HML) is an important technique enabling the generation of high‐
repetition‐rate ultrashort pulses. Using an emerging time‐stretch dispersive Fourier …

The year 2019 marks the 10th anniversary of the first report of ultrafast fiber laser mode-
locked by graphene. This result has had an important impact on ultrafast laser optics and …

Dissipative solitons are self-localized coherent structures arising from the balance between
energy supply and dissipation. Besides stationary dissipative solitons, there are dynamical …

Ultrashort optical pulses propagating in a dissipative nonlinear system can interact and bind
stably, forming optical soliton molecules. Soliton molecules in ultrafast lasers are under …

Q switching (QS) and mode locking (ML) are the two main techniques enabling generation
of ultrashort pulses. Here, we report the first observation of pulse evolution and dynamics in …
