设计了一种结构简单、成本低的 TW-EDFL(三波长掺铒光纤激光器),其输出波长分别为1530、1540 和 1550 nm,实现了1.5 mW 的稳定输出功率。研究了 EDF(掺铒光纤)长度和泵浦功率与输出功率的关系,得到最佳 EDF 长度为4.15 m、最佳泵浦功率为200 mW 的结论。在结构中加入3个 VOA(可变光衰减器),运用增益均衡的方法来平衡谐振腔内3路信号光的增益和损耗,避免了 EDF 在室温下的模式竞争效应。

This paper designs a simple-structured low-cost Triple-Wavelength Erbium-Doped Fiber Laser (TW-EDFL)with out-put wavelengths of 1 530,1 540 and 1 550 nm respectively and a stable output power of 1.5 mW.It investigates the relation-ship between the length of Erbium-Doped Fiber (EDF),pump power and output power and concludes that the optimum length of EDF is 4.1 5 m and the optimum pump power is 200 mW.It balances the gain and loss of 3 signal lights in the resonant cavi-ty by adding 3 Variable Optical Attenuators (VOA)and using the gain equalization method,thus avoiding the mode competi-tion effect of EDF at room temperature.
