N2 - Rare-earth elements (REEs) and other critical minerals (Li, etc.) form the basis of novel and sustainable energy sources. The development of sensitive, yet real-time detectors for improved mineral exploration and processing diagnostics will help meet this demand in an environmentally responsible manner. Laser-produced plasmas (LPPs) have proven to be a powerful tool for studying analytes. While laser-induced breakdown spectroscopy (LIBS) is a robust and widely established LPP-based sensor [1], it has limited resolution, which is critical when measuring the congested spectra of mineral samples. Dual-comb spectroscopy (DCS) is particularly suited to overcome this limitation, performing sensitive spectroscopy over broad spectral ranges [2]. Previous DCS characterization of REEs in LPPs were performed on metallic alloys with low oxygen content [3]. As the mineralogy of REEs includes oxygen and REEs themselves are excellent reducing agents, it is crucial to evaluate realistic mineral samples, for which changed ablation and LPP properties and therefore absorption spectra are expected.
