the ring-down time of a HeeNe laser beam passing through an optical cavity (Anderson et al., 1984). In 1988, O’Keefe and Deacon built the first cavity ring-down spectroscopy (CRDS) device using a pulsed laser, and successfully measured the spectrum of the oxygen molecule, marking the beginning of the CRDS technology (O’Keefe and Deacon, 1988).
