A traditional ultrafast fibre laser has a constant cavity length that is independent of the pulse
wavelength. The investigation of distributed ultrafast (DUF) lasers is conceptually and …

We report a passively Q-switched and mode-locked erbium-doped fiber laser (EDFL) based
on PtSe_2, a new two-dimensional material, as a saturable absorber (SA). Self-started Q …

Graphene, whose absorbance is approximately independent of wavelength, allows
broadband light–matter interactions with ultrafast responses. The interband optical …

Abstract Molybdenum disulfide (MoS2), whose monolayer possesses a direct band gap,
displays promising applications in optoelectronics, photonics, and lasers. Recent …

Controlled flexible pulses have widespread applications in the fields of fiber
telecommunication, optical sensing, metrology and microscopy. Here, we report a compact …

Layered metal dichalcogenides (LMDs) have received considerable attention in
optoelectronics and photonics. Tin disulfide (SnS 2) as a member of the LMDs has been …

We demonstrate the first 1.7 μm bismuth-doped fiber laser generating ultrashort pulses via
passive mode-locking. Pulse operation has been achieved for both anomalous and normal …

Black phosphorus (BP), a rising two-dimensional material with a layer-number-dependent
direct bandgap of 0.3–1.5 eV, is very interesting for optoelectronics applications from near-to …

Dissipative solitons, which result from the intricate balance between dispersion and
nonlinearity as well as gain and loss, are of the fundamental scientific interest and numerous …
