论文摘要
在这封信中，首次研究了近红外（近IIR和MID-IR）气体纤维拉曼激光器的噪声和长期稳定性的特征。结果表明，拉曼脉冲能量的增加与噪声的减少有关，并且相对脉冲峰强度噪声（RIN）始终低于相对脉冲能噪声（REN）。我们还证明，脉冲能量和峰值功率的长期漂移直接与拉曼·斯托克斯（Raman Stokes）生成期间的大量热量释放有关。所证明的噪声和长期稳定性性能为潜在的光谱应用提供了必要的参考，并进一步改善了新兴的中IR中IR气体填充的空心核纤维（HCF）RAMAN激光技术。
In this letter, the characteristics of noise and long-term stability of near- and mid-infrared (near-IR and mid-IR) gas-filled fiber Raman lasers have been investigated for the first time. The results reveal that an increase in Raman pulse energy is associated with a decrease in noise, and that the relative pulse peak intensity noise (RIN) is always lower than the relative pulse energy noise (REN). We also demonstrate that long-term drift of the pulse energy and peak power are directly linked with the high amount of heat release during the Raman Stokes generation. The demonstrated noise and long-term stability performance provide necessary references for potential spectroscopic applications as well as further improvements of the emerging mid-IR gas-filled hollow-core fiber (HCF) Raman laser technology.
