摘　　要：针对目前Fe^(2+):ZnSe激光器缺乏有效的高功率泵浦源这一关键瓶颈,提出了采用连续波HF化学激光器泵浦Fe^(2+):ZnSe来实现4μm波段激光输出的技术路线,结合实验和理论手段考察了此技术路线的可行性。首次获得了由连续波HF化学激光泵浦的Fe^(2+):ZnSe激光器的W级激光输出,输出功率约为1.7 W,谱线峰值波长为4.18μm,出光时间约2 s。In view of the key bottleneck that Fe^(2+):ZnSe laser lacks effective high-power pumping source at present,the technical route of using a continuous wave HF chemical laser to pump Fe^(2+):ZnSe to achieve laser output in 4μm band is proposed.The feasibility of this technical route is investigated both experimentally and theoretically.The output of a continuous wave HF chemical laser pumped Fe^(2+):ZnSe laser at watt level is obtained for the first time.The output power is about 1.7 W,the central wavelength is 4.18μm,and the lasing lasts about 2 s.
