中红外（IR）激光器是目前发展迅速的一个领域，有几种相互竞争的技术。在传统的气体激光器中，有效相互作用长度有限，系统整体体积大，不灵活，限制了其应用。标准增益光纤不能用于中红外，因为形成光纤芯的玻璃在这些较长波长处不透明。在这篇文章中，我们报告了在光腔中使用反馈的中红外光纤气体激光器的演示。该激光器采用高性能硅空心芯光纤中的乙炔气体作为增益介质，在被电信波长二极管激光器抽运时可发出连续波或同步抽运的激光。我们已经在3.1-3.2 μ m的光谱带中展示了许多跃迁的激光。该系统可以扩展到其他选定的分子物种，以产生高达5 μ m的光谱带输出，并且具有良好的功率缩放潜力。由美国光学学会根据知识共享署名4.0许可发布。
Mid-infrared (IR) lasers are currently an area of rapid development, with several competing technologies. In traditional gas lasers, the effective interaction length is limited and the system as a whole is bulky and inflexible, limiting their applications. Standard gain fibers cannot be used in the mid-IR because the glass forming the fiber core is not transparent at these longer wavelengths. In this Letter, we report the demonstration of a mid-IR fiber gas laser using feedback in an optical cavity. The laser uses acetylene gas in a high-performance silica hollow-core fiber as the gain medium, and lases either continuous wave or synchronously pumped when pumped by telecom-wavelength diode lasers. We have demonstrated lasing on a number of transitions in the spectral band of 3.1-3.2 mu m. The system could be extended to other selected molecular species to generate output in the spectral band up to 5 mu m, and it has excellent potential for power scaling.
