Evanescent Wave Cavity Ring-down Spectroscopy: A Future Technology for Process Sensing

Published

Author(s)

A C. Pipino, Joseph T. Hodges

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.
