摘要
多波长布里渊掺铒光纤激光器是一种新型的多波长光纤激光器,其原理是利用受激布里渊增益和掺铒光纤的线性增益,可以在常温下得到波长间隔约为0.08 nm(～10 GHz)的多波长输出.报道的布里渊掺铒光纤激光器,在布里渊抽运功率为1.7 mW、980 nm抽运功率为300 mW的情况下得到稳定的15个波长(间隔～10 GHz)的输出,这种激光器用作光传感器、光谱分析仪以及密集波分复用系统的光源.实验发现,输出波长的个数随着980 nm抽运功率的增大而增加.另外,布里渊掺铒光纤激光器的信号功率主要来自于掺铒光纤的增益,而布里渊增益对它的影响不大.
The Brillouin erbium-doped fiber laser is a novel kind of fiber laser with multi-wavelength output, which can produce a laser comb with spacing of 0.08 nm (10 GHz) using a combination of Brillouin gain and linear gain in erbium-doped fiber. The stabled 15-wavelength output are obtained with the Brillouin pump of 1.7 mW and 980 nm-pump of 300 mW. The laser can be utilized in optical sensor, spectrum analyser and dense wavelength division multiplexer system as laser source. The experiment also demonstrates that the number of output wavelength will increase when 980 nm pump increase and the power of multi-wavelength output mainly comes from the EDFA gain with little influence from Brillouin gain.
