摘　　要：基于半导体可饱和吸收镜,实现了3μm波段被动调Q光纤激光器平均功率瓦级输出。激光器最大平均功率为1.0 W,对应的最大脉冲能量及最大峰值功率分别为6.9μJ和21.7 W。激光器斜效率为17.8%,最高重复频率为146.3kHz,最小脉宽为315.0ns。A diode cladding pumped mid infrared passively Qswitched ErR＋ doped ZBLAN fiber laser with an average out put power of watt level based on a semiconductor saturable absorber mirror （SESAM） is demonstrated. Stable pulse train was produced at a slope efficient of 17.8% with respect to the launched pump power. The maximum average power of 1.0 W at a rep etition rate of 146.3 kHz was achieved with a corresponding pulse energy of 6.9 μJ. The maximum peak power was calculated to be 21.7 W.
