摘　　要：报道了波长可调谐增益开关中红外2．8μm脉冲光纤激光器。采用脉冲975nm半导体激光器泵浦高掺Er：ZBLAN双包层光纤，以闪耀光栅为谐振腔反馈元件，获得了波长可调谐增益开关中红外脉冲光纤激光输出。激光器工作频率为1～10kHz，波长调谐范围为2．703-2．819μm。在泵浦源重频10kHz条件下，激光器最大平均功率为110mw，最小脉宽为661．2ns，峰值功率为16．5W，斜率效率达28．6％。A wavelength-tunable and gain switched mid-infrared 2.8 μm fiber laser is intro- duced. The pulsed output is obtained from Er3＋-doped ZBLAN double-clad fiber pumped by a laser-diode（LD） with central wavelength of 975 nm. The wavelength and the repetition rate of the laser can be tuned in the range of 2. 703--2. 819 μm and 1--10 kHz, respectively. The maximum averaged output power of 110 roW, and the minimum pulse width of 661.2 ns are measured at the calculated peak power of 16.5 W, corresponding to a slope efficiency of 28.6% at a repetition of 10 kHz.
