摘要

在介绍光纤光栅波长调谐原理的基础上

设计了一种环形腔掺铒光纤激光器。利用光纤光栅(FBG)作为波长调谐元件

在20~170 ℃的温度范围内

实现了输出激光波长在1 547.7~1 556.5 nm内的连续可调

调谐线性度达99.96%

激光光谱的3 dB带宽均小于0.05 nm

20 dB带宽均小于0.08 nm

边模抑制比大于52 dB

输出功率可达21.2 mW。结果表明:可调谐掺铒光纤激光器具有可用带宽较宽、功率高、线宽窄、与光纤元件天然兼容等优点。

Abstract

Based on introducing the principle of wavelength tuning of FBG

a kind of ring Er-Doped Fiber Laser(EDFL) whose wavelength was tuned by FBG was designed. The output lasing wavelength between 1 547.7 nm and 1 556.5 nm can be tuned continuously within the temperature range from 20 to 170 ℃. The tuning linearity is up to 99.96%

the 3 dB linewidth is less than 0.05 nm and the 20 dB linewidth is less than 0.08 nm. While the side mode suppression ratio(SMSR) is more than 52 dB

the output power of EDFL is up to 21.2 mW. Experimental results show that the tunable EDFL has the advantages of wide bandwidth

high power

narrow linewidth and compatibility to fiber element.
