Abstract

We report on a mode-locked erbium-doped fiber laser suited to the generation of high-repetition-rate pulse trains or packets. The two-arm interferometer resonator performs a spectral filtering leading to the emission of short pulse packets with a high repetition rate, adjustable up to $200\mathrm{GHz}$. A continuous pulse train with a repetition rate of up to $6.9\mathrm{GHz}$ was obtained by adding a recirculation loop inside the cavity to fill the spaces between all pulse packets.
