We experimentally demonstrated that the stable dissipative solitons can be generated from the Yb-doped fiber laser with the interaction of mechanically exfoliated NbSe₂ and the evanescent field of the D-shaped fiber. The modulation depth of the saturable absorber with exfoliated layered NbSe₂ is 17.26% and the saturation intensity is 34.8 kW/cm², respectively. With the proposed saturable absorber, the Yb-doped fiber laser can deliver stable dissipative soliton with pulse duration 174 ps, repetition rate 14.7 MHz and signal-to-noise ratio 59.8 dB at the pump power 300 mW. The experimental results provide an insight for the ultrafast non-linear optical response of layered transition metal dichalcogenide, which may provide strategies for developing high-performance ultrafast non-linear optical devices.

我们实验证明，掺杂Yb的光纤激光器可以通过机械剥离NbSe ₂和D形光纤的the逝场之间的相互作用产生稳定的耗散孤子。剥离层状NbSe ₂的可饱和吸收体的调制深度为17.26％，饱和强度为34.8 kW / cm ²， 分别。使用提出的可饱和吸收器，掺Yb光纤激光器可以在泵浦功率为300 mW时以174 ps的脉冲持续时间，14.7 MHz的重复频率和59.8 dB的信噪比提供稳定的耗散孤子。实验结果为层状过渡金属二卤化硅的超快非线性光学响应提供了见识，这可能为开发高性能超快非线性光学器件提供策略。
