摘　　要：在环形腔主动锁模光纤激光器中引入啁啾光纤光栅。利用啁啾光纤光栅的大色散特性 ,通过调节调制频率 ,实现波长调谐 ,调谐范围 2nm。所得脉冲为重复频率 2 .5GHz ,脉宽约 6A wavelength tunable mode-locked fiber ring laser is described, in which a chirped fiber Bragg grating (CFGB) is included to give a large dispersion in the cavity. By the frequency modulating, the wavelength of pulse laser is tuned. The tuning range is about 2 nm, limited by the spectral band of CFBG. The pulses with positive chirp are obtained. The frequency of pulse is 2.5 GHz and pulse width is about 60 ps.
