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 thulium-doped fiber laser cavity is modulated by the optical injection at 1.55 μm via a nonlinear optical loop mirror in which a specially-designed...
The dynamics of dissipative solitons (DSs) are explored in a high-repetition-rate normal-dispersion erbium-doped fiber laser for the first time. Despite the high fundamental repetition rate of 129 MHz and, thus, the low pulse energy, a DS train with a dechirped pulse width of 418 fs, period doubling of single and dual DSs, and 258-MHz second-order harmonic mode locking of DSs, can be observed in the...
