Er^(3+)-Yb^(3+)共掺DBR光纤激光器的实验研究

Experimental study on Er^(3+)-Yb^(3+) co-doped fiber DBR laser

采用Er3+-Yb3+共掺单模光纤制作了DBR光纤激光器,有源光纤长度为10cm,光纤激光器为短腔结构。通过对不同前腔镜反射率的Er3+-Yb3+共掺DBR光纤激光器进行实验,得到了前腔镜反射率与激光器输出功率和阈值电流之间的关系,并对前腔镜反射率和有源光纤的长度的最优化选择进行了分析。

A fiber DBR laser using Er^3＋-Yb^3＋ co-doped fiber was fabricated. The fiber laser is short cavity with 10cm. The relationship between reflectivity of front cavity minor and output power and current threshold was verified by the experimental study of different reflectivity of front cavity minor. And the optimal selection for reflectivity of front cavity minor and active fiber length was analysed.
