Abstract

A polarization-maintaining (PM) fiber-coupled acousto-optic modulator (AOM) was used, in the present work, to tailor the stable 3.523 picosecond (ps) mode-locked pulses generated by an all PM fiber oscillator. The pulse clusters with 7.315 MHz, 731.5 kHz, and 73.15 kHz of repetition rate were obtained. The number of pulses in each pulse cluster could be adjusted from 1 to 6. Through the harmonic mode-locked (HML) technology, the tunability of the fiber laser was remarkably improved. Ultimately, the tunable number of pulses were extended to 8, 10, and 12, and obtained 4, 6 and 8 pulses with equal amplitude respectively, providing a greater flexibility than previous methods.
