摘要
论文采用布里渊泵浦光信号注入非线性光学环形镜(NOLM)中,进而构建线性腔结构的多波长掺铒光纤激光器。在此基础上,论文实验研究了掺铒光纤泵浦功率与布里渊泵浦功率对多波长掺铒光纤激光器输出波长数量的影响;以及NOLM中四分之一波片的角度对多波长掺铒光纤激光器波长输出数量和系统连续或脉冲工作状态的影响。通过计算SBS-NOLM效应的反射率,分析了调节四分之一波片改变多波长掺铒光纤激光器输出特性的机理。
The multiwavelength erbium - doped fiber laser (MEFL) with a linear cavity by seeding a Brillouin pump light signal into the nonlirear optical loop mirror (NOLM) . In such case, the impacts of erbium - doped fiber pump power and Brillouin pump power on the output number of the MEFL have been studied. The output number of the MEFL also can be controlled and the MEFL can work in mode - lock state by adjusting the quarter - plate angle. Furthermore, the mechanism of the MEFL has been analyzed by the reflection of the SBS - NOLM.
