摘　　要：基于非线性偏振旋转锁模技术,在掺铒环形光纤激光器中实验实现暗脉冲的产生.研究表明:暗脉冲的产生与掺铒环形光纤激光器的偏振控制器位置和抽运功率大小有密切的关系.暗脉冲的演化由光纤激光器增益与损耗的平衡引起.The generation of the dark pulses was experimentally investigated in an erbium-doped liber ring laser based on nonlinear polarization rotation technique.h was found that the dark pulses were related to orientation of the polarization controllers of the fiber ring laser.The evolution mechanism of dark pulses is caused by the modulation instability and the balance between gain and loss in the fiber ring laser.
