Abstract: We built a Tm:Ho co-doped fiber laser using a Ti₃C₂ MXene material as a saturable absorber (SA). The formation of vector solitons (VSs) and noise-like pulses (NLPs) was observed. The SA was prepared by dripping a Ti₃C₂ solution on a side-polished D-shaped fiber and then naturally vaporized. The VS is characterized by two coexisting sets of Kelly sidebands. By modulating the polarization controller in the fiber laser, NLPs with about 3.3 nm bandwidth can be switched from the VS. To the best of our knowledge, this is the first time that VSs have been generated in a fiber laser using a Ti₃C₂ MXene material as the SA.
