Stable, Ultrafast Pulse Mode-Locked by Topological Insulator <inline-formula> <tex-math notation="TeX">${\rm Bi}_{2}{\rm Se}_{3} $</tex-math></inline-formula> Nanosheets Interacting With Photonic Crystal Fiber: From Anomalous Dispersion to Normal Dispersion
We demonstrate two kinds of stable ultrafast fiber lasers mode-locked by topological insulator (TI) Bi<sub>2</sub>Se<sub>3</sub> nanosheets interacting with photonic crystal fiber (PCF). The saturable absorber (SA) produced by drying TI solution filled in 5.5 cm PCF provides...
