Cavity ring-down spectroscopy measures optical losses by the decay of the energy stored inside a cavity. The technique reaches unrivalled sensitivity because 

Cavity Ring-Down Spectroscopy (CRDS) Nearly every small gas-phase molecule (e.g., CO 2, H 2 O, H 2 S, NH 3) has a unique near-infrared absorption spectrum. At sub-atmospheric pressure,

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

Cavity ring-down spectroscopy (CRDS) is an established technique for gas sensing that is newly emerging in the field of optical biosensing.

We present the development, integration, and testing of an open-path cavity ring-down spectroscopy (CRDS) methane sensor for deployment on small unmanned 

In this pilot work, we present a lung cancer detection framework using cavity ring-down spectroscopy (CRDS), an effective and practical laser absorption spectroscopy technique that has the ability to advance breath screening into clinical reality. The main aims of this work were to 1) test the utility of infrared CRDS breath profiles for
