Evanescent-Wave Cavity Ring-down Spectroscopy for Trace Water Detection

February 1, 2001
Author(s)
A C. Pipino, Joseph T. Hodges
We explore the use of evanescent wave cavity ring-down spectroscopy (EW-CRDS) for water detection through a signal-to-noise ratio analysis. Cavity ring-down spectroscopy (CRDS) is an emerging optical absorption technique that employs the mean photon decay

Pulsed, Single-Mode Cavity Ringdown Spectroscopy

June 1, 1999
Author(s)
Roger D. van Zee, Joseph T. Hodges, J P. Looney
This paper demonstrates an implementation of single mode cavity ring-down spectroscopy, using a pulse laser system, with near shot-noise limited sensitivity. The rationale for this approach is discussed, the experimental apparatus is described, and the

Measuring Pressures With Cavity Ring-Down Spectroscopy

January 1, 1998
Author(s)
Roger D. van Zee, J P. Looney, Joseph T. Hodges
The industrial demand for sensitive and noninvasive tools with which to measure pressure has spurred the use of optical methods to make these measurements. This paper reviews these industrial needs, and discusses how cavity ring-down spectroscopy can be
