We report on an all-fiber, actively mode-locked, tunable, Thulium-doped, fiber laser based on a 20-GHz bandwidth electro-optic intensity modulator (EOM) and a voltage driven 2-μm, intra-cavity, fiber-coupled, Fabry-Perot tunable filter (FFP-TF). The repetition rate of output pulses was 47 MHz and the shortest measured output pulse width was 445 ps. A continuous tuning range of 88 nm has been achieved from 1954 to 2042 nm with a spectral linewidth ≤0.14 nm and an optical signal-to-noise ratio <55 dB. The fiber laser offers an amplitude stability of ±0.2 dB and a wavelength stability of ±0.02 nm over 2 hours.
