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.
