A Dual-Comb Spectroscopy System for the Detection of Rare-Earth Minerals
We present a laser ablation dual-comb spectroscopy system for the detection of rare-earth elements and other critical minerals with high spectral resolution (1.9 GHz or 1.6 pm) in the 518 nm – 532 nm range. A proof-of-concept measurement for multi-species detection within a Cu alloy matrix containing La, Ce, and Sm is demonstrated. A comparison with results from studies using REE within their naturally occurring mineralogical matrices as well as levels of detection will be discussed.
