Scanless quantum Fourier-transform mid-infrared spectroscopy for solids and surface analysis
Paul Gattinger, Michela Conti, Franziska Dietz +4
Quantum infrared (IR) spectroscopy is a novel technique based on nonlinear interferometry and quantum sensing with undetected photons. In this approach, spectrally far-separated co…
Scanless quantum Fourier-transform mid-infrared spectroscopy for rapid high-sensitivity hyperspectral mapping
Paul Gattinger, Bettina Heise, Andreas W. Schell +3
Fourier-transform infrared (FTIR) spectroscopy is a well-established technique for qualitative and quantitative chemical analysis. Classical FTIR systems rely, however, on direct m…
Systematic Investigation and Suppression of Fluorescence in High-Sensitivity Cavity-Enhanced Raman Gas Sensing
Severin Hager-Roiser, Robert Zimmerleiter, Paul Gattinger +3
Raman spectroscopy enables broadband, multi-species gas analysis by providing access to an entire vibrational spectrum in a single measurement. However, the sensitivity of gas-phas…
Dispersion in nonlinear interferometry: implications for optical coherence tomography with undetected photons
Ivan Zorin, Paul Gattinger
Nonlinear SU(1,1) quantum interferometers based on non-degenerate optical parametric down-conversion exhibit strong unbalanced group velocity dispersion (GVD). This feature is intr…
Quantum Fourier Transform Infrared Spectroscopy: Evaluation, Benchmarking and Prospects
Paul Gattinger, Andreas W. Schell, Sven Ramelow +2
Sensing with undetected photons has enabled new, unconventional approaches to Fourier transform infrared (FTIR) spectroscopy. Leveraging properties of non-degenerated entangled pho…
All-mirror wavefront division interferometer for mid-infrared spectrometry
Ivan Zorin, Paul Gattinger, Giovanna Ricchiuti +3
We report on the design of an all-mirror wavefront-division interferometer capable of spectroscopic studies across multiple spectral ranges$\unicode{x2013}$from the plasma frequenc…
Advances in mid-infrared spectroscopy enabled by supercontinuum laser sources
Ivan Zorin, Paul Gattinger, Alexander Ebner +1
Supercontinuum sources are all-fiber pulsed laser-driven systems that provide high power spectral densities within ultra-broadband spectral ranges. The tailored process of generati…
Time-encoded mid-infrared Fourier-domain optical coherence tomography
Ivan Zorin, Paul Gattinger, Andrii Prylepa +1
We report on a technically simple approach to achieve high-resolution and high-sensitivity Fourier-domain OCT imaging in the mid-infrared range. The proposed OCT system employs an…
Frequency-domain optical coherence tomography with undetected mid-infrared photons
Aron Vanselow, Paul Kaufmann, Ivan Zorin +3
Mid-infrared light scatters much less than shorter wavelengths, allowing greatly enhanced penetration depths for optical imaging techniques such as optical coherence tomography (OC…
Correlative infrared optical coherence tomography and hyperspectral chemical imaging
Ivan Zorin, Rong Su, Bettina Heise +2
Optical coherence tomography (OCT) is a high-resolution three-dimensional imaging technique that enables non-destructive measurements of surface and subsurface microstructures. Rec…
