英文摘要	基于游标原理,利用一对自由谱宽(fSr)略有不同的光纤布喇格光栅法布里-珀罗腔(fbg-fP)作为模式选择器件,设计了一种新颖的环形腔光纤激光器。从理论和实验上研究了该激光器的特性。通过对可调谐fbg-fP应力调谐,在1552.240~1552.912 nM范围内,以96 PM为平均间距,获得了8个由固定fbg-fP的透射谱所确定的窄线宽稳定激光输出。8个输出波长的平均功率为-17.66 dbM,波动在0.7 db范围内。当泵浦光的功率为95 MW的时候,输出信号的信噪比均大于50 db。实验上每隔1 MIn用光谱分析仪(OSA)对输出光波长自动扫描,记录的输出光波长漂移在数皮米范围内,且功率的波动小于0.1 db。这种可调谐的窄线宽光纤激光器在光纤通信和光纤传感方面有潜在的应用价值。; Using a pair of Fiber Bragg grating Fabry-Pérots(FBG-FP)with a little different FSR as its wavelength-selective components,a novel ring laser based on the vernier effect is proposed.We have studied the characteristics of this kind of tunable fiber laser both theoretically and experimentally,and obtained 8 discretely tunable laser wavelengths ranging from 1552.240 nm to 1552.912 nm with an average 96 pm span by pulling the tunable FBG-FP.The output spectrum peak is uniform among different wavelength at-17.66 dBm with a fluctuation of 0.7 dB.When the pump power is 95 mW,the signal-to-noise ratio is better than 50 dB.The output spectrum of the laser is recorded automatically by an optical spectrum analyzer(OSA)once a minute.It is found that the output wavelength drift within a few pico-meter and the fluctuation of the output power is less than 0.1 dB.This kind of fiber ring laser may have potential applications in optical communications and sensors.; 国家自然科学基金项目(No.61077031/F050208); 福建省教育厅B类科技研究项目(No.JB11097)资助
