实验研究了长腔全正常色散掺镱光纤环形腔激光器的不同工作状态。通过调节偏振控制器（PC）和泵浦功率，获得了各种工作状态。获得了自脉冲、亮脉冲、暗-亮脉冲对及其对应的谐波锁模（HML），以及暗脉冲及其对应的谐波锁模。数值模拟很好地再现了暗脉冲和暗-亮脉冲对的形成过程。
We have investigated experimentally different operational states of an all-normal-dispersion ytterbium-doped fiber (YDF) ring laser with a long cavity. Various operational states were obtained by adjusting a polarization controller (PC) and the pump power. Self-pulsing, bright pulses, dark-bright pulse pairs and their harmonic mode locking (HML) counterparts, as well as dark pulses and their HML counterparts have all been obtained. Numerical simulations reproduce well the formation processes of dark pulses and dark-bright pulse pairs.
