Abstract

We report on the generation and propagation of stretched-pulse in an erbium-doped fiber laser with near-zero dispersion. The pulse exhibits broadband spectrum with sidebands on long-wavelength side, which may be attributed to the strong gain and loss perturbations induced by the long cavity. After the extra-cavity propagation via a 19-m single-mode fiber (SMF), the spectrum of pulses almost keeps unchanged whereas the pulse duration broadens from 0.22 to 6.33 ps, indicating that fiber dispersion plays a key role in pulse propagation. Moreover, the evolution of pulse duration in SMF is in good agreement with that of theoretical predictions. This pulse evolution through extra-cavity fiber is quite different from the evolution of dissipative solitons, in which the pulses are compressed rather than broadened.
