All-Optical Actively Mode-Locked Fiber Laser at 2-μm Based on Interband Modulation

In this paper, we have achieved a high repetition rate and tunable pulse generation near ∼2 μm through an all-optical actively mode-locked fiber laser. The performances of the fiber laser have been systematically investigated through numerical simulations. The thuliu...
