Abstract
A cavity enhanced optical detector comprising: i) a source of continuous wave laser light; ii) a high finesse resonant cavity comprising at least three spaced apart, high-reflectivity mirrors positioned to receive light from the laser light source; iii) at least one photo-detector for measuring the extinction coefficient of an analyte that is positioned in the resonant cavity; and iv) one or more additional photo-detectors for measuring the intensity of fluorescence emission and/or Raman scattering from the analyte.
