Numerical study of a rational harmonical mode-locked semiconductor optical amplifier fiber ring laser

摘要

Based on the self-reproduction theory, a rational harmonic mode-locked semiconductor optical amplifier fiber ring laser was numerically investigated. The system parameters effects on pulse-amplitude equalization of rational harmonic mode locking was analyzed and the numerical result shows that the 2 similar to 5 order rational harmonic mode-locked pulse with the small amplitude ripple can be obtained only by adjusting the system parameters.
