Direct frequency comb cavity ring-down spectroscopy: Enhancing Sensitivity and Precision
Romain Dubroeucq, Dominik Charczun, Piotr MasÅowski +1
We present a novel approach to cavity ring-down spectroscopy utilizing an optical frequency comb as the direct probe of the Fabry-Perot cavity, coupled with a time-resolved Fourier…

Sub-Doppler optical-optical double-resonance spectroscopy using a cavity-enhanced frequency comb probe
Vinicius Silva de Oliveira, Isak Silander, Lucile Rutkowski +4
Accurate parameters of molecular hot-band transitions, i.e., those starting from vibrationally excited levels, are needed to accurately model high-temperature spectra in astrophysi…

Measurement and assignment of J = 5 to 9 rotational energy levels in the 9070-9370 cm range of methane using optical frequency comb double-resonance spectroscopy
Adrian Hjältén, Vinicius Silva de Oliveira, Isak Silander +6
We use optical-optical double-resonance (OODR) spectroscopy with a continuous wave (CW) pump and a cavity-enhanced frequency comb probe to measure high rotational energy levels of…
