摘要： In this paper, the self-startlng mode-locking characteristics of all-fiber lasers are in-vestigated theoretically. The mechanism of self-starting mode-locking is analyzed and the experimental phenomena are explained successfully by introducing effective energy gain. The modulation characteristics of all-fiber lasers and the effect of gain saturation on modulation characteristics are discussed by analyzing the transmissivity of Er-doped fiber loop. Finally, the dynamic processes of all-fiber self-starting mode-locked lasers are simulated numerically.
