摘　　要：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1 530、1 540和1 550nm,实现了1.5mW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4.15m、最佳泵浦功率为200mW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.
