2294 nm End-Pumped ZnWO4 Raman Laser
摘要
报道了一种采用ZnWO4单晶作为拉曼晶体的2294 nm拉曼激光器。使用激光二极管端面抽运Tm∶YLF晶体产生1899 nm的基频光,采用内腔抽运ZnWO4晶体,得到了2294 nm的一阶斯托克斯激光输出,最大功率为173 mW,最短脉宽为2.280 ns,最高峰值功率为25.292 kW,从实验上证实了ZnWO4作为红外拉曼晶体的可行性。
Abstract
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.
