Abstract

Two mode-lock regimes are observed experimentally and theoretically in the all-normal-dispersion fiber lasers: strong- and weak-modulation regimes. The pulse properties of these two regimes are investigated and summarized. The weak-modulation regime provides stable mode-locked pulses with picosecond pulse duration and broad spectrum linewidth. It well fits the chirped-pulse amplification as a seed source. An all-fiber all-normal-dispersion fiber ring laser is established. Stable mode-locked pulses with a pulse duration of 75 ps and a linewidth of 17.8 nm are obtained. The experimental results have a good agreement with the weak-modulation regime predicted in theory.
