摘要
研究并设计了一种双程双向C+L波段高平坦度光纤光源,以两个980nm半导体激光器为抽运源,使用双向泵浦的方法对掺铒光纤进行泵浦,再由光纤反射镜反射之后,得到了C+L波段的自发放大辐射谱。通过调整980nm半导体激光器的输出功率和掺铒光纤的长度,得到在1525~1600nm的范围内,在不添加任何增益平坦滤波器的情况下,自发放大辐射谱的平坦度达到2dB,总的输出功率达到15.58mW的宽带光。
This paper studied and designed a two-stage two-way C＋L band flatness high fiber source, using two 980nm semiconductor lasers as pumping sources, and the erbium-doped fiber is pumped by a bidirection- al pump. After reflection, the spontaneous emission spectrum of C＋L band is obtained. By adjusting the output power of the 980nm semiconductor laser and the length of the erbium-doped fiber, the flatness of the self-amplified radiation spectrum reaches 2dB in the range of 1525-1600nm without addition of any GFF, and the total output power reached 15.58mW of broadband light.
