Vector soliton and noise-like pulse generation using a Ti3C2 MXene material in a fiber laser

We built a Tm:Ho co-doped fiber laser using a Ti 3 C 2 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 Ti 3 C 2 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 Ti 3 C 2 MXene material as the SA.
