摘　　要：报道利用Er∶Yb双掺杂光纤制作的单频窄线宽分布布拉格反射 (DBR)光纤激光器。在 980nm半导体激光器抽运下 ,当抽运功率为 75mW时 ,获得了输出功率为 2 3mW的单频激光 ,其中心波长为 1 5 5 7 5 2 4nm ,线宽小于 5MHz。利用制作的单频DBR光纤激光器构成光纤有源传感系统 ,进行温度传感实验研究 ,实验结果线性度很好 。A narrow-line width single-frequency distributed Bragg reflection (DBR) fiber laser was fabricated using Er:Yb codoped fiber. The laser was pumped by a semiconductor laser operated at 980 nm and an output power of 2.3 mW with line-width less than 5 MHz was obtained when pump power was 75 mW. Wavelength of the laser is 1557.524 nm. An active fiber sensor based on the DBR fiber laser was applied for temperature sensing and the experimental results show good linearity. This system has the merit of easier wavelength-detection owning to its high signal-to-noise ratio and output power.
