Ultraviolet Dual Comb Spectroscopy: A Roadmap
arXiv:2006.03309 · doi:10.1364/OE.424940
Abstract
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 - 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.
