Triple-Resonance Spectroscopy Using a Cavity-Enhanced Frequency Comb Probe
Qinxue Nie, Vinicius Silva de Oliveira, Adrian Hjältén +3
Accurate experimentally verified models of molecular hot-band transitions are essential for interpreting high-temperature spectra in environments ranging from exoplanetary atmosphe…
Measurement and assignment of 10 rotational energy levels in the 9510 to 9810 cm and 6590 to 6900 cm ranges of methane using optical frequency comb double-resonance spectroscopy
Yuan Cao, Adrian Hjältén, Vinicius Silva de Oliveira +4
The paper reports measurements and assignments of methane rotational transitions with J ≥ 10 using optical‑optical double‑resonance spectroscopy combined with a cavity‑enhanced fre…
Rotational energy levels in the ground vibrational state of methane with kHz-level accuracy from comb-referenced double-resonance and Lamb-dip spectroscopies
Vinicius Silva de Oliveira, Isak Silander, Hiroyuki Sasada +4
Methane is a key spherical-top molecule, yet restrictive selection rules for one-photon transitions have prevented determination of its ground state (GS) energies with state-of-the…
Optical frequency comb double-resonance spectroscopy of the 9030-9175 cm states of ethylene
Adrian Hjältén, Vinicius Silva de Oliveira, Yuan Cao +3
We use optical-optical double-resonance (OODR) spectroscopy to measure for the first time hot-band transitions of ethylene (CH) between states in the 3000 cm and…
Measurement and assignment of E-symmetry states in the 6010-6110 cm and 8940-9150 cm ranges of methane using optical frequency comb double-resonance spectroscopy
Adrian Hjältén, Vinicius Silva de Oliveira, Michael Rey +3
We use sub-Doppler optical-optical double-resonance (OODR) spectroscopy with a 3.3 m single-frequency pump and a cavity-enhanced 1.65 m comb probe to measure 33 ladder-type…
Combined frequency comb and continuous wave cavity-enhanced optical-optical double-resonance spectrometer in the 1.7 m range
Vinicius Silva de Oliveira, Adrian Hjältén, Isak Silander +4
We present an optical-optical double-resonance (OODR) spectrometer based on a 3.3 m continuous wave pump and two cavity-enhanced probes: a frequency comb tunable in the 1.64 -…
