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。

Abstract

This paper designs a simple-structured low-cost Triple-Wavelength Erbium-Doped Fiber Laser（TW-EDFL）with output wavelengths of 1 530

1 540 and 1 550 nm respectively and a stable output power of 1.5mW.It investigates the relationship between the length of Erbium-Doped Fiber（EDF）

pump power and output power and concludes that the optimum length of EDF is 4.15 mand the optimum pump power is 200 mW.It balances the gain and loss of 3signal lights in the resonant cavity by adding 3Variable Optical Attenuators（VOA）and using the gain equalization method

thus avoiding the mode competition effect of EDF at room temperature.
