The broadband and high-resolution absorption spectra of molecular cerium oxide (CeO) are obtained using dual-comb spectroscopy in a laser-produced plasma. Simultaneous measurements of Ce and CeO are used to investigate the time-resolved dynamics of the system. The high spectral resolution allows for the simultaneous detection of numerous closely spaced rotational transitions in complex CeO bands.
Broadband and high-resolution absorption spectra of molecular cerium oxide (CeO) are obtained in a laser-produced plasma using dual-comb spectroscopy. Simultaneous measurements of Ce and CeO are used to probe time-resolved dynamics of the system. A spectral resolution of 1.24 GHz (2.4 pm) over a bandwidth of 378.7-383.7 THz (781.1-791.5 nm) allows simultaneous detection of hundreds of closely spaced rotational transitions in complex CeO bands.
