| description | The saturable absorber of niobium diselenide (NbSe<sub>2</sub>), with a wide working bandwidth and excellent nonlinear optical response, was prepared using liquid-phase exfoliation. Its saturation intensity and modulation depth were 5.35 MW/cm<sup>2</sup> and 6.3%, respectively. Stable mode-locking with a center wavelength of 1558.7 nm of an erbium-doped fiber laser based on a NbSe<sub>2</sub> saturable absorber was successfully achieved. The maximum average output power of the mode-locked laser was 6.93 mW, with a pulse width of 1.3 ps and a repetition rate of 25.31 MHz at a pump power of 550 mW. The results show that NbSe<sub>2</sub> is a promising photoelectric modulation material owing to its excellent nonlinear optical properties. |
