Abstract
Evanescent wave cavity ring-down spectroscopy (EW-CRDS) is described. The total internal reflection (TIR)-ring and monolithic folded cavity designs are briefly discussed. The performance of EW-CRDS for trace water vapor detection is evaluated by accounting for surface chemical and physical properties as well as intrinsic resonator properties.
