摘要
提出一种新型的掺铒光纤环形激光器,利用全光纤马赫曾德尔干涉仪选频,并将掺铒光纤浸在液氮中冷却,得到了稳定的7个波长的激光输出,波长间隔为0.65nm。
A novel structure of multiwavelength fiber ring laser is proposed, which utilizes erbium doped fiber cooled by liquid nitrogen and all fiber M Z interferometer. The simultaneous oscillation of seven wavelengths with spacing of 0.65 nm was obtained.
