In this work, we present a high-pulse-energy multi-wavelength Raman laser spanning from 1.53 µm up to 2.4 µm by employing the cascaded rotational stimulated Raman scattering effect in a 5 m hydrogen ()-filled nested anti-resonant fiber, pumped by a linearly polarized Er/Yb fiber laser with a peak power of ∼13 and pulse duration of ∼7 in the C-band. The developed Raman laser has distinct lines at 1683 nm, 1868 nm, 2100 nm, and 2400 nm, with pulse energies as high as 18.25 µJ, 14.4 µJ, 14.1 µJ, and 8.2 µJ, respectively. We demonstrate how the energy in the Raman lines can be controlled by tuning the pressure from 1 bar to 20 bar.
在这项工作中，我们通过在一根5米长的充氢（）嵌套反谐振光纤中利用级联旋转受激拉曼散射效应，呈现了一种高脉冲能量的多波长拉曼激光器，其波长范围从1.53微米到2.4微米，由一个在C波段峰值功率约为13且脉冲持续时间约为7的线偏振铒/镱光纤激光器泵浦。所研制的拉曼激光器在1683纳米、1868纳米、2100纳米和2400纳米处有明显的谱线，脉冲能量分别高达18.25微焦、14.4微焦、14.1微焦和8.2微焦。我们展示了如何通过将压力从1巴调至20巴来控制拉曼谱线中的能量。
