摘要
基于半导体可饱和吸收镜,实现了3 μm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6.9 μJ和21.7 W.激光器斜效率为17.8%,最高重复频率为146.3 kHz,最小脉宽为315.0 ns.
Abstract
A diode-cladding-pumped mid-infrared passively Q-switched Er3+-doped ZBLAN fiber laser with an average output 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 repetition 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.
