We demonstrated a passively Q-switched 2.8-mu m Er3+-doped ZBLAN fiber laser with topological insulator Bi2Te3 nanosheets prepared by the solvothermal method. Enabled by the gold mirror with self-assembled Bi2Te3 nanosheets film sandwiched by polymethyl methacrylate polymer, the Q-switched fiber laser can deliver a maximum average power of 856 mW with corresponding pulse energy of 9.3 mu J and a pulse width of 1.3 mu s at a repetition rate of 92 kHz under the pump power 5.9 W. To the best of our knowledge, this is the highest output power for the pulsed fluoride fiber laser around 2.8 mu m modulated by the two-dimensional Dirac material. This letter reveals that the topological insulator can be a kind of promising nonlinear modulator for a mid-infrared laser.
