论文摘要
一般而言,自我扫描效果依赖于增益纤维中形成的动态光栅。在这里,正常的自扫循环是在无泵的Ytterbium掺杂纤维中产生的,该纤维可作为纤维饱和吸收剂,并在该实验中由循环器引入激光腔。清晰的速率和扫描范围像往常一样改变,这两者都可以由泵功率控制。此外,在这项工作中观察并讨论了一个新的自渗水信号,该信号显示了活性纤维和可饱和吸收剂之间的自扫效应的差异。
Generally speaking, the self-sweeping effect relies on the dynamical grating formed in a gain fiber. Here, the normal self-sweeping was generated in a pump-free ytterbium-doped fiber which serves as a fiber saturable absorber and is introduced to the laser cavity by a circulator in this experiment. The sweeping rate and the sweeping range alter as usual, both of which can be controlled by the pump power. Further, a new self-pulse signal is observed and discussed in this work, which shows the difference of the self-sweeping effects between active fiber and fiber saturable absorber.
