摘要
We report an all-fiber thulium-doped wavelength-tunable mode-locked laser operating near 2 mu m. Reliable self-starting mode locking over a large tuning range (>50 nm) using a fiber-taper-based carbon nanotube saturable absorber is observed. Spectral tuning is achieved by stretching another fiber taper. To the best of our knowledge, this is the first demonstration of an all-fiber wavelength tunable mode-locked laser near 2 mu m.
