We have coupled a commercially available cavity ring-down spectroscope (CRDS) (Picarro G5101-I isotopic N2O analyzer) to an air/water gas 

Cavity ringdown spectroscopy (CRDS), a laser absorption spectroscopic technique,for many round trips within the cavity, thus effectively enhancing the laser beam absorption path-length by several orders of magnitude. (CRDS is considered being one of many cavity enhanced absorption spectroscopy methods). Therefore, the detection sensitivity is

4/1 · Cavity ring-down spectroscopy (CRDS) provides an ideal solution for determining the reflectance of highly reflective optics by measuring the total loss of the optic, which includes

Cavity ring-down spectroscopy (CRDS) is a direct absorption technique with a signifi- cantly higher sensitivity than conventional absorption spectroscopy. It is based on the measurement of the rate of absorption, rather than the magnitude of absorption, of light circulating in an optical cavity. Let us consider a simple CRDS experiment.
