Tunable, high-repetition-rate, harmonically mode-locked ytterbium fiber laser

This is the authors' abstract. We don't add key points for this paper.

We report a ytterbium fiber laser mode locked at its 281st harmonic, which corresponds to a repetition rate greater than 10 GHz. The laser produces linearly polarized, 2-ps pulses with up to 38-mW of average output power. The mode-locked pulses are tunable over a 58-nm window centered on 1053 nm.
