| 摘 要： | 在光纤光栅制作过程中,宽带光源经常被应用于在线监测光纤光栅的反射率,以便适时有效地控制生成的光栅的透射率的高低程度.利用中心波长为971nm的半导体激光器抽运一段Yb+掺杂双包层光纤,制作出了一个宽带超荧光光源,该光源在最大功率输出时谱宽达到了75nm,并在1085nm附近10nm范围内荧光谱的输出功率高,有较好的光谱平坦性.还利用该宽带光源作为光纤光栅制作的监控光源,制作出了单模和多模光纤布喇格光栅,取得了令人满意的实验结果.结果表明,该宽带光源完全可以适应监控光纤光栅制作的需要.

| Abstract: | Broad bandwidth source(BBS) is usually used to watch and control the fabrication of fiber gratings.A home-made Yb~(3 )-doped double-cladding fiber superfluorescent broad bandwidth source is reported.The BBS,with bandwidth of about 75nm at the maximum output power,is pumped by a 971nm laser diode.The BBS outputs high power with a flat superfluorescent spectrum in the range of 10nm near the central wavelength of 1085nm.Then the BBS is used to watch and control the fabrication of single-mode and multi-mode fiber Bragg gratings and the results are satisfied. |
