Large-area highly crystalline WSe2 atomic layers for ultrafast pulsed lasers.
Optics Express, 2017 Large-area and highly crystalline transition metal dichalcogenides (TMDs) films possess superior saturable absorption compared to the TMDs nanosheet counterparts, which make them more suitable as excellent saturable absorbers (SA) for ultrafast laser ...

Colloidal Plasmonic Nanoparticles for Ultrafast Optical Switching and Laser Pulse Generation
Frontiers in Materials, 2018 Light-matter interactions are greatly enhanced and spatially well-confined in plasmonic nanostructures in the spectral resonance range. In colloidal plasmonic nanoparticle (NP), this effect is manifested by the strong absorption caused by the collective ...

Graphene-clad microfibre saturable absorber for ultrafast fibre lasers
Scientific Reports, 2016 Graphene, whose absorbance is approximately independent of wavelength, allows broadband light–matter interactions with ultrafast responses. The interband optical absorption of graphene can be saturated readily under strong excitation, thereby enabling ...
