Precision electric-field-resolved infrared spectroscopy

Ioachim Pupeza

MPI für Quantenoptik, Germany

The talk addresses recent progress in mid-infrared field-resolved spectroscopy driven by high-power MHz-repetition-rate femtosecond lasers. Intrapulse difference-frequency generation (IPDFG) delivers trains of Watt-level few-cycle mid-infrared optical waveforms with sub-attosecond jitter. Electro-optic sampling (EOS) with multi-Watt short-wave mid-infrared gate pulses allows for recording these waveforms with high fidelity, and with sensitivities close to the fundamental quantum limit. This renders the combination of IPDFG and EOS ideal for tracing light-matter interactions on their native time scales, as well as for broadband vibrational fingerprinting of molecular samples with unprecedented sensitivity and dynamic range.

We report the measurement and assignment of sub-Doppler transitions in the 3ν3 ← ν3 band of methane using optical-optical double resonance spectroscopy with a 3.3 µm continuous wave pump and a 1.67 µm frequency comb probe. We implement an optical cavity for the comb probe that improves the sensitivity by more than two orders of magnitude compared to previous measurements in a single-pass cell.

Electro-optic Dual-Comb Spectrometer for Applications in the Mid-Infrared

Alexandre Parriaux, Kamal Hammani, Guy Millot

Laboratoire Interdisciplinaire Carnot de Bourgogne (ICB), UMR6303 CNRS, Université Bourgogne Franche-Comté, Dijon, France

We present a dual-comb setup operating in the mid-infrared between 4.2µm and 4.85µm based on the frequency conversion of combs generated around 1.56µm by intensity modulation. We show that the spectrometer can be used for high-resolution spectroscopic applications enabling isotopic ratio measurements, but also towards the medical domain.

High-resolution optical frequency comb Fourier transform spectroscopy in the near- and mid-infrared wavelength range

Aleksandra Foltynowicz

Department of Physics, Umea University, Sweden

We use Fourier transform spectroscopy based on frequency combs to measure broadband spectra with resolution limited by the comb mode width. In the near-infrared, we measured mode profiles of a high-finesse cavity over 15 THz of bandwidth with 3 kHz resolution, and derived absorption and dispersion spectra of three CO2 bands from the broadening and shift of the cavity modes. In the mid-infrared, we measured and assigned absorption spectra of CH3I around 3.3 µm, and we retrieved transition frequencies of N2O and CH4 around 7.8 µm with precision <200 kHz.
