利用单模光纤的非线性效应——背向受激布里渊散射(BSBS)和光纤光栅的选频特性，用掺铒单模光纤作增益介质，采用半导体激光器连续抽运方式，研究了自调Q光纤激光器的运转情况，得到了稳定的光脉冲输出。脉冲宽度(FWHM)约为2.2 ns，重复频率为64.5 MHz。

Self-Q-switched Er-doped fiber laser has been studied in this paper. Er-doped fiber is applied as gain medium, which is pumped by CW 980 nm LD. A fiber grating is used as the wavelength selector and cavity reflector. The stable self-Q-switched laser output is realized based on the nonlinearity of SM fiber—stimulated Brillouin scattering. The repetition rate about 64.5 MHz, and the full width at half maximum (FWHM) about 2.2 ns are obtained.
