摘要：

We investigate the characteristics of dispersion-tuning in an actively mode-locked fiber ring laser. A continuous tuning range over 20 mm at about 1-GHz operation is realized, The range can be extended by optimizing the polarization to attain a flattened spectral gain in the Er-doped fiber. The influence of the harmonic order of operation together with the amount of dispersion in the fiber ring have been experimentally studied. Rational harmonic mode-locking is first demonstrated in the dispersion-tuned laser to increase the output repetition rate. Our results agree well with theory, showing that dispersion-tuning is a reliable, economic, and effective way to generate widely tunable pulses.
