论文摘要
双梳光谱证明了其在不同光谱区域的分子指纹中的多功能能力，但尚未在紫外线（UV）中。解锁此光谱窗口将向物质的电子能量结构扩展指纹。这将访问具有前所未有的光谱分辨率的光化反应的主要触发器。在这篇研究文章中，我们讨论了通往第一个UV双梳光谱仪的方式的里程碑。我们提出了针对紫外线双梳光谱的实验和模拟研究，直接应用于甲醛（以343 nm，3.6 eV）和Argon（80 nm，16 eV）的计划吸收测量。这将使无与伦比的相对分辨率高达$ 10^{ - 9} $ - ，一个台式紫外线源超过了至少两个和任何基于光栅的紫外线光谱仪的任何同步子链接的光谱仪，最多可达六个幅度。
Dual Comb Spectroscopy proved its versatile capabilities in molecular fingerprinting in different spectral regions, but not yet in the ultraviolet (UV). Unlocking this spectral window would expand fingerprinting to the electronic energy structure of matter.This will access the prime triggers of photo-chemical reactions with unprecedented spectral resolution. In this research article, we discuss the milestones marking the way to the first UV dual comb spectrometer. We present experimental and simulated studies towards UV dual comb spectroscopy, directly applied to planned absorption measurements of formaldehyde (centered at 343 nm, 3.6 eV) and argon (80 nm, 16 eV). This will enable an unparalleled relative resolution of up to $10^{-9}$ - with a table-top UV source surpassing any synchrotron linked spectrometer by at least two and any grating-based UV spectrometer by up to six orders of magnitude.
