摘要：
We use a rapidly swept optical cavity in a novel approach to cavity ringdown spectroscopy (CRDS) with a continuous-wave (cw) laser. This simplifies cw-CRDS by eliminating the need for a fast optical switch and is demonstrated by recording weak combination-band spectra of carbon dioxide diluted in nitrogen, using a cw single-mode tunable diode laser (TDL) in the 1.55 mu m near-infrared region. We employ a simultaneous combination of CRDS and cavity-enhanced absorption spectroscopy, to compensate for nonlinear CRDS response that is observed for stronger absorption features. Experimental results and performance characteristics are presented, together with numerical simulations. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
