The birth of spatiotemporal mode-locking (STML) can date back to the report of Wright and colleagues in 2017. Following this breakthrough, research on STML has thrived. However, our comprehension and ...

Mode-locked lasers are advanced lasers that produce very short pulses of light, with durations ranging from femtoseconds to picoseconds. These lasers are widely used to study ultrafast and nonlinear ...

Ultrafast lasers have become powerful tools in various fields, and increasing their fundamental repetition rates to the gigahertz (GHz) level holds great potential for frontier scientific and ...

Here we consider coherent mode-locking (CML) regimes in single-section cavity lasers, taking place for pulse durations less than atomic population and phase relaxation times, which arise due to ...

Mode-locked fibre lasers, featuring ultrafast temporal information, ultrahigh peak energy, and exceptional stability, have become essential tools in modern optics and industries, including ...

Saturable absorbers as passive modulators in passively mode-locked fiber lasers play a crucial role in the generation of ultrashort pulses. Germanene, a graphene-like two-dimensional material with ...
