摘　　要：报道了包层泵浦调Q光纤激光器的实验研究。采用连续光泵浦方式,在激光谐振腔中,利用多模硅光纤中的非线性效应-受激Brillouin散射(SBS)进行自调Q,得到了纳秒量级的脉冲输出;改用脉冲光泵浦方式,实现了重复频率连续可调,稳定的纳秒量级光脉冲输出,脉宽(FWHM)小于2ns,峰值功率大于8kw。A cladding pumped Yb^(3+) fiber laser operating in a Q-switched regime with a tunable repetition rate is described. By exploiting fiber nonlinearity-stimulated Brillouin Scattering(SBS) process in the laser cavity. Pules duration shorter than 2 ns were achieved. The repetition rate was stable and adjustable by the pump source. And the peak power of more than 8 kW pulses were obtained.
