We demonstrate an all fiber high-repetition-rate erbium-doped ultrashort laser based on the Ti₃C₂T _x -Mxene saturable absorber (SA), and the 56th harmonic mode-locking with a repetition rate of 622.2MHz, a central wavelength of 1590.7nm, and a pulse duration of 1.31ps is achieved. Meanwhile, dual-wavelength mode-locking pulses are also realized, with the central wavelengths of 1575.6, 1587.5nm. The results of the work indicate that Ti₃C₂T _x -Mxene is an outstanding SA for generating ultrashort pulse or modulating the light and the diversity Mxene family can bring new vigor and vitality into advanced photonic devices.
