Abstract We report a cladding-pumped Tm3+-doped domestic silica fiber laser operated at 2 µm and actively Q-switched with an acousto-optic modulator. Pulse trains are obtained as pumped by a 785 nm laser diode. The maximum average output power is 1.27 W. Peak power up to 4.2 kW and pulse energy up to 840 µJ are obtained with the pulse duration of 200 ns produced at a repetition rate of 1 kHz. The laser performance is studied under different repetition rates and pump powers. Lastly, we give some discussion.
