A new generation of ultrafast and low-noise supercontinuum (SC) sources is currently emerging, driven by the constantly increasing demands of spectroscopy, advanced microscopy, and ultrafast photonics applications for highly stable broadband coherent light sources. In this Perspective, we review recent progress enabled by advances in nonlinear optical fiber design, detail our view on the largely untapped potential for noise control in nonlinear fiber optics, and present the noise fingerprinting technique for measuring and visualizing the noise of SC sources with unprecedented detail. In our outlook, we highlight how these SC sources push the boundaries for many spectroscopy and imaging modalities and focus on their role in the development of ultrafast fiber lasers and frequency combs with ultra-low amplitude and phase noise operating in the 2 μm spectral region and beyond in the mid-IR.

下一代超低噪声光纤超连续谱光源及其在光谱、成像和超快光子学中的新兴应用展望

由于光谱学、先进显微镜和超快光子学应用对高度稳定的宽带相干光源的需求不断增长，新一代超快和低噪声超连续谱 (SC) 光源正在出现。在这个视角中，我们回顾了非线性光纤设计的进步所带来的最新进展，详细介绍了我们对非线性光纤中大量未开发的噪声控制潜力的看法，并提出了用于测量和可视化 SC 源噪声的噪声指纹技术细节。在我们的展望中，我们将重点介绍这些 SC 源如何突破许多光谱和成像模式的界限，并重点关注它们在开发超快光纤激光器和频率梳中的作用，这些激光器在 2 μ m 光谱区域以及中红外区域以外的区域。
