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.
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 such 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.
