Description
Summary:As a new member of transition metal dichalcogenides (TMDs), rhenium disulfide (ReS ), with a nearly unchanged direct bandgap from bulk to monolayer form, is attractive in physics and material fields. By using the optically driving deposition method, the ReS saturable absorber (SA) has been fabricated with a modulation depth and saturation fluence of 6.9% and 27.5 μJ/cm , respectively. Based on the ReS -SA, a multi-wavelength bright-dark pulse pair from a mode-locked fiber laser has been observed experimentally for the first time, to the best of our knowledge. The saturable absorbing ability of the ReS is attributed to the formation of the bright pulses and the dark pulses. The cross-phase modulation (XPM) caused by different wavebands of bright pulse and dark pulse support the coexisting of the bright-dark pulse pair.
