We demonstrated the tunable passively Q-switched Thulium-Flouride Fiber (TFF) laser based on exfoliated MoS2 saturable absorber (SA).  The generation of Q-switched pulses of the proposed experiment favors the tunable operation from 1460.0 nm to 1506.0 nm, with range of 46.0 nm. The achievable maximum repetition rate and maximum pulse energy in the experiment are 35.1 kHz and 63.2 nJ, respectively. To the best of our knowledge, the first reported tunable passively Q-switched TFF laser using exfoliated MoS2 as saturable absorber has been demonstrated.
