most recent spectroscopy techniques allows to get ideal metrological probes to measure extremely low
concentrations of rare molecules. The best results have been obtained in the last few years with saturated-absorption cavity ring-down (SCAR)\footnote{\href{https://link.aps.org/doi/10.1103/PhysRevLett.104.110801}{10.1103/PhysRevLett.104.11080}, Giusfredi, G. and Bartalini, S. and Borri, S. and Cancio, P. and Galli, I. and Mazzotti, D. and De Natale, P., \textit{Saturated-Absorption Cavity Ring-Down Spectroscopy}, Phys. Rev. Lett. 104, 11, 110801, 
(2010).}, a nonlinear cavity ring-down technique, to detect the very elusive
$^{14}$CO$_2$. Indeed, this radioactive molecule amounts only to about 1 part in $10^{12}$, as compared to the overall
CO$_2$ in the biosphere. Therefore, the sensitivity achieved by SCAR, of a few parts in $10^{15}$, provides a wide
dynamic range for radiocarbon dioxide detection, challenging the best results provided by Accelerator Mass
Spectrometry (AMS)\footnote{\href{https://opg.optica.org/optica/abstract.cfm?URI=optica-3-4-385}{10.1364/OPTICA.3.00038}, I. Galli, S. Bartalini, R. Ballerini, M. Barucci, P. Cancio, M. De Pas, G.
