In this experiment, the Zirconium Diselenide (ZrSe₂) was successfully manufactured as the saturable absorber (SA), the modulation depth and saturable intensity of 3.94% and 13.38 MW/cm⁻², for demonstrating single-, dual-wavelength pulses within an Er-doped fiber laser (EDFL). The pulse duration of single-wavelength pulses was approximately 1.65 ps. The central wavelengths of dual-wavelength pulses were 1559.4 and 1559.8 nm. The results fully suggested that ZrSe₂ nanosheets have widely potential in ultra-fast pulse lasers due to its excellent saturable absorber characteristics.
