摘要
实验观测了掺Yb3+双包层光纤激光器的时域特性和光谱特性.研究了抽运功率、腔损耗对激光器工作特性的影响.研究发现,利用单镜腔结构的光纤激光器,可产生自脉动、受激布里渊散射和受激喇曼散射等非线性效应;而采用双镜腔结构可有效抑制自脉动特性,提高激光器工作的稳定性,并对实验现象进行了定性的分析.
Abstract
The temporal and spectral characteristic of a Yb doped double clad fiber laser has been studied. The influences of the pumped power and the cavity losses on the laser are investigated. It is found that the self pulsing and the nonlinear phenomena shch as Brillouin and Raman scatterings can be observed in a one mirror cavity, and the system is stabilized in a two mirrors cavity where Brillouin and Raman scatterings are efficiently suppressed. We also give a theoretical explanation about the phenomenon in our experiments.
