摘　　要：采用中心波长为975nm半导体激光器泵浦高掺铒氟化物双包层光纤Er：ZBLAN，并在谐振腔内插入主动调Q元件，获得了工作频率为1～10kHz的2．8μm激光主动调Q脉冲输出．在工作频率为10kHz条件下，获得了最大单脉冲能量为134．5μJ、脉宽为127．3ns、峰值功率为1．1kW的脉冲输出．A high peak power actively Q-switched mid-infrared fiber laser at 2.8 μm was demonstrated with a repetition rate of 1-10 kHz by employing a 975 nm laser-diode to pump a piece of heavily Er^3＋ - doped ZBLAN double-clad fiber and a mechanical chopper into the cavity as the Q-switch. Stable Q- switched laser pulse with a maximum pulse energy of 134.5 μJ, pulse duration of 127.3 ns and peak power of 1.1 kW was obtained at a repetition rate of 10 kHz under a proper pump power.
