Fourier transform cavity ring-down spectroscopy using an optical frequency comb source
Résumé
We demonstrate a new broadband multiplexed cavity ring-down approach based on a near-infrared frequency comb source and a time-resolved Fourier transform spectrometer. We apply the technique to spectroscopy of atmospheric CO2 and H2O. © Optica Publishing Group 2022, © 2022 The Author(s)
