Abstract
We discuss how the frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) method enables high-precision and high-sensitivity measurements of shapes, intensities, as well as broadening and shifting parameters of absorption lines} 73, 012507 2006.}. We illustrate the method's high spectral resolution by observation of sub-MHz wide Doppler-free saturation features in blended near-ir H$_2$O spectra, and we present measurements and models of H$_2$O and O$_2$ spectra that yield line parameters with sub\%-level relative uncertainties.
