Abstract
Cavity enhanced spectroscopy efficiently couples a broadband optical frequency comb to a high finesse optical cavity inside which a sample test gas is placed. The output of the optical cavity is a multiplicity of channels of data resulting from the differential absorption of light at various of the comb frequencies. The device can operate in a ringdown mode or a non-ringdown enhanced absorption spectroscopy mode. Careful measurement and control of cavity dispersion and comb spacing are part of the coupling process. Several dispersive detection methods adapted to detecting the multiplicity of channels are provided.
