摘　　要：对高掺铒光纤激光器的输出特性进行了研究 .实验中观察到随泵浦能量增加 ,激光器由连续运转变为脉动输出 (微秒量级 ) .继续增加泵浦能量 ,在展开的脉冲包络中观察到了纳秒调制信号 ,其宽度小于 2 ns.用离子对交叉驰豫模型及光纤中的非线性效应—受激布里渊散射对实验结果进行了定性解释 .The characteristics of the output pulses from high Er doped Fiber (EDF) lasers are demonstrated in this paper. When the pumping threshold is reached, CW operation of the laser is achieved. With the increasing of the pumped power a series of stable μs pulses are observed and then the ns pulses are obtained. The results are explained qualitatively by the cross relaxation model of ion pair and the fiber nonlinearity stimulated Brillouin scattering.
