Abstract

Abstract: Detection of systematic errors of the measurement method is a demanding task, since it requires an independent, high-accuracy reference method for comparison. Here, we validate the cavity ring-down spectroscopy (CRDS) in relation to the one-dimensional cavity mode-dispersion spectroscopy (1D-CMDS). The complex line-shape function is used for the first time in the simultaneous analysis of absorptive and dispersive spectra and its potential in accurate line-shape studies is indicated. A new approach providing insensitivity of the 1D-CMDS to the drift of the laser-to-cavity locking point is demonstrated.
