Dual-comb absorption spectroscopy of molecular CeO in a laser-produced plasma

Not Accessible

Your library or personal account may give you access

Abstract

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.
