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 ...

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 ...

Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement ...
