摘要

摘要: 短线腔掺铒光纤激光器由环形器(OC)、自制的Bi3+Ga3+Al3+共掺高浓度掺铒光纤(BiGaAl-EDF)、均匀光纤布拉格光栅(UFBG)和波分复用器(WDM)组成。以OC作为全反射腔镜，UFBG为波长选择性部分反射腔镜，利用1 530 nm处吸收系数为84.253 dB/m 的BiGaAl-EDF为增益介质，室温下获得了中心波长为1 544.31 nm、边模抑制比(SMSR)大于55 dB的激光输出。分析了BiGaAl-EDF长度对激光器输出特性的影响。结果表明：采用12 cm长的光纤实现了短线腔的窄线宽激光输出，在25 cm长度下，该激光器具有最小的起振阈值和最大的输出功率。测试表明，该短线腔激光器具有线性输出特性，并且其中心波长和输出功率不随时间的变化而发生漂移。

Abstract: A simple and effective short linear cavity erbium-doped fiber laser was presented. The laser consisted of an optical circulator (OC), a segment of self-made high concentration erbium-doped fiber co-doped with Bi3+Ga3+Al3+(BiGaAl-EDF), a uniform fiber Bragg grating (UFBG), and a wavelength division multiplexing(WDM). By using the OC as an all-reflection mirror and the UFBG written directly in the G652 fiber as a partial-reflection mirror and a wavelength selector, a stable wavelength oscillation with a center wavelength of 1 544.31 nm and a side mode suppression ratio (SMSR) of about 57 dB is achieved at room temperature. The impact of the length of BiGaAl-EDF on the laser’s output characteristic was analyzed. With a 12 cm long BiGaAl-EDF as the gain medium
