Overview

abstract

  • Dual-comb spectroscopy in the ultraviolet (UV) and visible would enable; broad bandwidth electronic spectroscopy with unprecedented frequency; resolution. However, there are significant challenges in generation,; detection, and processing of dual-comb data that have restricted its; progress in this spectral region. In this work, we leverage robust; 1550 nm few-cycle pulses to generate frequency combs in the; UV–visible. We combine these combs with a wavelength; multiplexed dual-comb spectrometer and simultaneously retrieve 100 MHz; comb-mode-resolved spectra over three distinct harmonics at 386, 500,; and 760 nm. The experiments highlight the path to continuous dual-comb; coverage spanning 200–750 nm, offering extensive access to; electronic transitions in atoms, molecules, and solids.
