飞秒被动锁模光纤激光器的稳定性研究

Stability of Passively Modelocked Femtosecond Fiber Laser

摘要: 从广义非线性薛定谔锁模方程出发，运用数值方法分别研究了泵浦光功率和非线性饱和吸收体对飞秒被动锁模光纤激光器工作特性的影响，并得到了激光器在基阶脉冲重复频率下稳态输出的最高输入泵浦功率和其对应的非线性饱和吸收体稳定工作区间。该研究结果为进一步优化设计最高泵浦功率、非线性饱和吸收体开关以及提高被动锁模光纤激光器的稳定工作性能都具有指导意义。

Abstract: The stability of passively modelocked femtosecond fiber laser affected by different factors,especially pump power and fast saturable absorber, has been thoroughly studied in this paper. The results show that it is necessary to make laser work with proper driving of fast absorber and mediate pumping power for stable pulse output.
