We demonstrated an all-fiber mode-locked Thulium–Holmium co-doped fiber laser (THDFL) based on molybdenum disulfide (MoS2) tape saturable absorber. The THDFL generates a mode-locked pulse in anomalous regime at 1,979[Formula: see text]nm using 5[Formula: see text]m long Thulium–Holmium co-doped (THDF) as a gain medium. Through mechanical exfoliation method, the MoS2 was mechanically extracted from a commercial MoS2 crystal by using a clear scotch tape. Through balanced twin-detector measurement, the obtained MoS2 tape has a nonlinear absorption of 10% with 100[Formula: see text]MW/cm2 saturation intensity. Under 775[Formula: see text]mW to 852[Formula: see text]mW pump power, a stable pulse train was obtained at 9.12[Formula: see text]MHz repetition rate with a signal-to-noise ratio (SNR) of 45[Formula: see text]dB. The maximum output power and pulse energy were measured about 20[Formula: see text]mW and 2.2[Formula: see text]nJ, respectively. With a 3-dB spectral bandwidth of 2.1[Formula: see text]nm, the minimum possible pulse width was determined as 1.97[Formula: see text]ps.

We demonstrate a Q-switched Erbium-doped fiber laser (EDFL) using a molybdenum disulfide (MoS[Formula: see text]-based saturable absorber (SA) as a Q-switcher. The SA is prepared from commercial available MoS2 pristine flakes with final solution concentration of [Formula: see text]0.02[Formula: see text]mg/ml. The Q-switcher is assembled by depositing a dried MoS2 onto a fiber ferule facet before it is matched with another clean ferrule via a connector. By increasing the pump power from 120[Formula: see text]mW to 160[Formula: see text]mW, stable generation of Q-switched EDFL incorporating MoS2 SA has been obtained at 1502[Formula: see text]nm wavelength. The pulse repetition rate also varies from 45.2[Formula: see text]kHz to 66.0[Formula: see text]kHz with pulse width which is increased from 2.73[Formula: see text][Formula: see text]s to 3.19[Formula: see text][Formula: see text]s. At pump power of 160[Formula: see text]mW, we successfully generated the maximum average output power of 0.51[Formula: see text]mW, corresponding to a pulse energy of 7.8[Formula: see text]nJ.
