Dissipative Soliton Generation From Yb-Doped Fiber Laser Modulated by Mechanically Exfoliated NbSe2

Abstract

We experimentally demonstrated that the stable dissipative solitons can be generated from the Yb-doped fiber laser with the interaction of mechanically exfoliated NbSe 2 and the evanescent field of the D-shaped fiber. The modulation depth of the saturable absorber with exfoliated layered NbSe 2 is 17.26% and the saturation intensity is 34.8 kW/cm 2 , 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.

Picosecond dissipative soliton generation from an ytterbium-doped fiber laser based on a BP/SnSe2-PVA mixture saturable absorber

“…The system could deliver stable dissipative solitons with pulse duration of 174 ps, repetition rate of 14.7 MHz, and SNR of 59.8 dB at pump power of 300 mW. These excellent experimental results demonstrate that the 2D material indeed has a good ultrafast nonlinear optical response and has great potential for the study of dissipative solitons [ 10 ].…”

Highly Stable Passively Q-Switched Erbium-Doped All-Fiber Laser Based on Niobium Diselenide Saturable Absorber

“…Compared with the TMD materials with semiconductor properties, 2D nanostructured TMDs with metal layers, such as NbS 2 and NbSe 2 , exhibit lower fabrication cost, stronger optical absorption, and higher carrier mobility [ 23 , 24 , 25 , 26 ]. Recently, NbSe 2 has been clearly proven to have good saturable absorption properties in the spectral range from 1 to 1.5 μm, due to ultra-fast saturation recovery time and wide absorption band [ 27 , 28 , 29 , 30 ]. Furthermore, NbSe 2 has excellent environmental stability, so it is very helpful for generating long-term stable laser pulses, especially in fiber lasers.…”
