Abstract

International audience; Cavity ringdown spectroscopy (CRDS) has been widely used for three decades as a high sensitivity spectroscopy technique. It is usually used with narrow-linewidth light sources, allowing high resolution and spectral density, but requiring long acquisition times for a wide spectral coverage due to laser diode tuning delays. A broadband light source would offer a multiplex acquisition along CRDS advantages.We have developed a new CRDS technique based on a fast-scan time-resolved Fourier transform spectrometer (FTS), an optical cavity and a frequency comb source in the NIR region. The comb is locked to the cavity to ensure continuous output transmission. We present our latest results with atmospheric CO2 at ambient temperature.We achieve a noise-equivalent absorption of 1.5 × 10-8 cm-1 for a single acquisition of 25 s with a resolution of 592 MHz over a spectral bandwidth of 20 cm-1. This yields a noise-equivalent absorption sensitivity of 2.4 × 10-9 cm-1 Hz-1/2 per spectral element.

Abstract

International audience; Highly accurate measurements of H2 transition frequencies is fundamental for testing the quantum electrodynamics and physics beyond the standard model [1-3]. However, the retrieval of the un-perturbed line positions is very challenging since it compels to work in low pressure conditions: the achievement of high signal-to-noise ratios is then hindered by the weakness of quadrupole transition moments and by the low molecular density. Alternatively, the distortion of the line profile at higher pressure could be carefully modelled in order to compensate for speed-dependent collisional effects and for the strong Dicke narrowing. High accuracy measurements of the Q(1) transition of the pure H2 1-0 band at 4155.25 cm-1 have been performed from 0.2 to 5 atmosphere using stimulated Raman spectroscopy. An Er:fiber frequency comb has been used to calibrate the frequency difference between the pump and Stokes cw lasers involved in the Raman process. The pump laser emits at 737.8 nm and is kept fixed while the Stokes laser is scanned over 3 GHz around 1064 nm. The two beams are spatially superimposed and travel through a multipass cell filled with H2. Figure 1 (a) displays the line profiles measured at seven different pressures (the measurements at the two lowest pressures are displayed in the inset). As it can be noticed from panel (b) the retrieved widths are in a good agreement with ab-initio values based on H2-H2 quantum scattering calculations. The frequency shift, plotted in panel (c), is proportional to pressure above 1 atm and the retrieved pressure coefficient agrees well with previous results [4]. The strength of the approach which provides high signal-to-noise ratio and frequency accuracy at the same time enables the use of more advanced profile models, such as the Hartmann-Tran profile, for line shape investigation.

Abstract

An absorption spectrum of (H2O)-O-16 at 1950 K is recorded in a premixed methane/air flat flame using a cavity-enhanced optical frequency comb-based Fourier transform spectrometer. 2417 absorption lines are identified in the 6250-6670 cm(-1) region with an accuracy of about 0.01 cm(-1). Absolute line intensities are retrieved using temperature and concentration values obtained by tunable diode laser absorption spectroscopy. Line assignments are made using a combination of empirically known energy levels and predictions from the new POKAZATEL variational line list. 2030 of the observed lines are assigned to 2937 transitions, once blends are taken into account. 126 new energy levels of (H2O)-O-16 are identified. The assigned transitions belong to 136 bands and span rotational states up to J = 27.

Abstract

We report the measurement of sub-Doppler double-resonance transitions in methane using a 3.3 $\mu$m continuous wave optical parametric oscillator to pump transitions in the fundamental $\nu_3$ band and a 1.67 $\mu$m frequency comb to probe ladder-type transitions in the 3$\nu_3$ band over 200 cm$^{-1}$ of bandwidth. We detected 36 ladder-type resonances for 9 pumped transitions with average center frequency accuracy of 1.7 MHz, limited by the pump frequency stability. The lines are assigned using the TheoReTS line list, and the intensity ratios for different relative pump/probe polarizations. This method provides accurate assignment of highly excited energy levels that cannot be done using high temperature spectra.
