Abstract

We report tunable active harmonic mode-locking of a dissipative soliton ytterbium-doped fiber laser based on a high-speed intensity modulator with all-normal-dispersion (ANDi) cavity. Adjusting the working frequency and the data length of radio driving signals for the dissipative soliton pulses shaping, the repetition rates can be facilely and accurately scalable from 20.33 to 609.84 MHz corresponding to the harmonic order from the fundamental rate to 30th, which is higher than the passive harmonic mode-locking (HML) fiber laser in an all-fiber and ANDi cavity. The cavity supermode-suppression ratio is suppressed up to 50 dB, and the signal-to-noise ratio is better than 57 dB at the 30th HML.
