摘　　要：对谐波锁模半导体光放大器(SOA)光纤环形激光器的工作条件提出改进,并采用自再现理论对其进行了数值研究。数值结果表明:激光器在新的工作条件下,即调制SOA被高直流偏置,对自发辐射信号进行调制并提供锁模脉冲克服腔损耗所需的增益,而此时的增益SOA被低直流偏置充当增益补偿器,输出的锁模脉冲质量显著提高。An improvement to the work condition of harmonic mode-locked SOA fiber ring lasers was presented and was numerically investigated based on the self-reproduction theory. The numerical result shows that the lasers on the new work condition, namely, the modulation SOA is biased on the high direct current, whereas the gain SOA is biased on the low direct current functions as a gain compensator, can generate a high-quality pulse trains. After obtaining the optimal work condition, the characteristic of harmonic mode-locked （HML） pulse on the different bias current of the modulation SOA were investigated.
