摘　　要：报道了一种基于微结构光纤(MF)的光纤环激光器。通过微调控制信号的频率,激光器实现了稳定的锁模状态,在C波段获得了重复频率为10 GHz、宽度小于8 ps的相干光脉冲输出。在该激光器中,采用了掺Er光纤放大器(EDFA)作为腔内增益介质,并使用了25 m长、具有反常色散和高非线性的MF作为脉冲压缩介质。通过调整腔内的带通滤波器中心频率可以实现对工作波长的连续调谐,因此该激光器可作为波分复用(WDM)系统的可调谐光源。We present a fiber ring laser based on microstructure fiber（MF）. By slightly adjusting the frequency of control signahthe active mode-locked state is acquired,and the laser can produce correlated optical pulses with high repetition rate of 10 GHz and narrow width of less than 8 ps. In this laser,erbiurrrdoped fiber amplifier（EDFA） is usede for optical gain,and a 30 m long MF is used for pulse compression,which has a large anomalous dispersion and a high nonlinear coefficient. The operating wavelength can be altered by changing the central wavelength of the band-pass filter in the fiber ring,So this laser can be used as the tunable optical source for wavelength -division-multiplexing（WDM） systems.
