Mode-locked lasers generate short pulses of intense coherent light. Just like a guitar string, laser cavities can support many different frequencies, or resonant modes. A train of picosecond or ...

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 ...
