We present the recent research progresses of our group on mid-infrared pulsed fiber lasers at 3 μm by passive switching. Three different kinds of saturable absorbers including semiconductor saturable absorber(SESAM), Fe2+:Zn Se crystal, and topological insulator(TI) were used to perform the pulse generation, respectively. The temporal regimes of mode locking, Q-switching, and Q-switching induced gain switching were gained. Some relative discussions and prospective efforts are proposed at the end of this paper.
