N2 - In this work we demonstrate the first application of dual-comb spectroscopy in the deep ultraviolet (UV) in a time-resolved measurement of a laser-produced plasma (LPP) generated from a metal alloy target. We further show DCS absorption measurements utilizing intra-cavity high-harmonic generation (iHHG) from passive femtosecond enhancement cavity's (fsEC) [1] to demonstrate the approach can be extended into the VUV and XUV. The UV/VUV region contains a rich number of strong atomic and ionic transitions originating from ground and low-energy states of many elements. High-resolution studies in this spectral region are needed in many scientific studies, as well as for characterization of solid materials. Nonetheless, there is a significant lack of spectroscopic information in this region compared to the visible and near-IR. Our work extends DCS to the UV for precision time-resolved studies of LPP's for the first time, and paves the way for extension into the VUV and XUV.
