ABSTRACT=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 nonlinear optical response of layered transition metal dichalcogenide, which may provide strategies for developing high-performance ultrafast nonlinear optical devices.
