Graphdiyne has an inborn band gap energy, where the minimal band gap is about from 0.46
to 1.22 eV, which shows great potential in ultrafast laser generation. In this work, we …

We report the generation of dissipative soliton resonance and soliton rain in an Er-doped
fiber laser based on GeTe as saturable absorber. When the pump power is 60 mW, the fiber …

As a Dirac material, an allotrope of graphene, namely γ-graphyne (γ-GY), is proved to have
excellent nonlinear optical properties. Unfortunately, the saturable absorption properties and …

We report the generation of dual-wavelength conventional solitons (CSs) in an erbium-
