Keyword:  光纤光栅滤波器环形掺铒光纤激光器波长可调谐;
Abstract: 研制了一种新型的高性能环形可调谐光纤光栅激光器.该激光器使用980nm LD作为泵浦源,使用长度为10.8m的新型增益平坦掺铒光纤作为增益介质,采用可调谐光纤光栅滤波器进行波长调谐,调谐范围可达41nm(1528nm~1569nm),中心波长可精确调谐到C波段指定的ITU-T标准中心波长处,3dB带宽<0.08nm,25dB带宽<0.2nm,波长稳定性优于0.01nm,边模抑制比>60dB.最大输出功率46.94mW,功率稳定性优于±0.02dB,阈值泵浦功率7.3mW,斜率效率为39.75%.并分析了不同腔长、不同输出耦合比对输出功率的影响.
