Abstract
Various embodiments provide devices and methods of an optical coupled-cavity photo-acoustic spectroscopy (CC-PAS). The exemplary CC-PAS can include three mirrors configured in parallel to couple a Fabry-Perot (FP) cavity with a sample cavity. The sample cavity can be a resonant cavity for containing a sample. The FP cavity can be used as a tunable input coupler for the sample cavity to improve spectroscopic sensitivities when measuring an absorber in the sample.
