Remote isotope detection and quantification using femtosecond filament-laser ablation molecular isotopic spectrometry

We demonstrate the detection and quantification of isotopes from solid samples remotely at a distance 36 m. This was accomplished through combination femtosecond filaments laser ablation molecular isotopic spectrometry (F 2 -LAMIS). Isotopically enriched graphite with varying 13 C concentration were used F -LAMIS emission measured using fieldable spectrometer system. A standardless approach to determine corresponding ratios. The use for atmospheric pressure without calibration standards opens possibility implement this technology remote sensing in field applications. • F2-LAMIS is Insight into filament-material interaction extended distances by studying craters. 13C isotopically are measurements. Isotope ratios quantified approaches based on spectral line fitting. These findings open detect
