Saykally21 Los Gatos Research,  67 East Evelyn Ave., Mountain View,  CA  940412 Department of Chemistry, University of California, Berkeley, CA 94720Cavity Ringdown Spectroscopy has become a widely usedtechnique in the optical absorption analysis of atoms, molecules,and optical components.  The technique allows the determination oftotal optical losses within a closed cavity comprised of two or moremirrors, and can be made arbitrarily more sensitive by improvmentsin the cavity mirror reflectivity.  Part of the great attraction thatCavity Ringdown has, in addition to its’ great sensitivity, is thesimplicity of it’s use.  The required equipment is modest, and thetheory of operation is easily grasped by students of modest training.In fact, the technique is used at a growing number of universities asan undergraduate laboratory demonstration.  This article presents areview of the development of the Cavity Ringdown technique fromits’ roots as an unstable and difficult to use method of measuringmirror reflectivities, to the development of the high sensitivitypulsed and continuous adaptations which are in current use.
