Abstract :
We have developed a technique to measure trace concentrations of gases in the near-infrared region using Continuous Wave Excitation Cavity Ring-down Spectroscopy (CW-CRDS). We have demonstrated that with a simple CW-CRDS system, trace amounts of moisture (water vapor) can be accurately detected.
