摘要: 设计实现了一种编程扫描宽调谐掺铒光纤激光器,波长扫描调谐范围超过51nm(1516.83—1568.31nm),调谐步长最小可达0.01nm,通过编程控制波长重复扫描调谐。将该激光器应用于光纤光栅组成准分布式温度传感系统,初步实验实现了对16路共48个点的实时温度监测。

Abstract: A programmable wavelength widely tunable Er-doped fiber laser is demonstrated. The tunable range can cover above 51nm (1516.8—1568.3nm) controlled by software and tunable step is up 0.01nm. The laser and fiber Bragg grating (FBG) make up quasi-distributed temperature sensing system, which is applied in power system to achieve real-time temperature of 16 fibers channels, a total of 48 monitoring points.
