摘　　要：报道了一种采用ZnWO_4单晶作为拉曼晶体的2294nm拉曼激光器。使用激光二极管端面抽运Tm:YLF晶体产生1899nm的基频光,采用内腔抽运ZnWO_4晶体,得到了2294nm的一阶斯托克斯激光输出,最大功率为173mW,最短脉宽为2.280ns,最高峰值功率为25.292kW,从实验上证实了ZnWO_4作为红外拉曼晶体的可行性。A 2294 nm Raman laser using ZnWO4 crystal as Raman crystal is reported. The Tm∶YLF crystal is used to generate the fundamental laser at 1899 nm, and the intracavity pumping on ZnWO4 crystal is adopted to obtain the first-order Stokes laser at wavelength of 2294 nm. The maximum power, shortest pulse width, and corresponding peak power are 173 mW, 2.280 ns, and 25.292 kW, respectively. The feasibility of ZnWO4 as infrared Raman crystal is verified experimentally.
