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

摘要：本文利用Ti3C2 MXene材料作为可饱和吸收体，搭建了铥钬共掺光纤激光器，观察到矢量孤子和类噪声脉冲的形成。其中，可饱和吸收体是通过将Ti3C2溶液滴在侧面抛光的D形光纤上自然挥发后制备而成。观察到的矢量孤子光谱上同时存在两组Kelly边带。通过调节光纤激光器中的偏振控制器，可以将矢量孤子转变为光谱带宽约3.3 nm的类噪声脉冲。据我们所知，这是首次利用Ti3C2 MXene材料作为可饱和吸收体从光纤激光器中获得矢量孤子。
