摘　　要：报道了一种高重复频率全光纤非线性偏振旋转锁模掺铒光纤激光器,获得了重复频率217 MHz的锁模脉冲输出.该激光器使用一个偏振相关隔离器和一个偏振控制器即可获得稳定的锁模脉冲输出,结构简单,系统稳定.激光器锁模脉冲的脉冲宽度为69 fs,3 dB光谱宽度为56 nm,射频频谱信噪比为76 dB.We demonstrate a high-repetitiomrate Er-doped all fiber laser with nonlinear-polarization-rotation mode-locking. The highest repetition rate of the laser is 217 MHz. The fiber laser has a very simple and compact structure and can output a stable mode-locking pulse only by using one polarization-dependent isolator and a polarization controller. The pulse width, spectral width and signal-to-noise ratio are measured to be 69 fs, 56 nm and 76 dB respectively.
