Supercontinuum sources based on intrapulse difference frequency generation (IDFG) from mode-locked lasers open new opportunities in mid-infrared gas spectroscopy. These provide high power and ultra-broadband spectral coverage the molecular fingerprint region with very low relative intensity noise. Here, we demonstrate performance of such a light source combination multipass cell custom-built Fourier transform spectrometer (FTS) for multispecies trace detection. The provides low-noise,...
Wastewater treatment plants significantly contribute to greenhouse gas emissions, including nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4). Current methods measure these emissions typically target specific molecular compounds, providing limited scope potentially incomplete profiles. Here, we show an innovative ultra-broadband coherent open-path spectroscopy (COPS) system capable of simultaneously monitoring multiple gases. This novel approach combines Fourier transform with a...

Novel mid-infrared nonlinear-fiber-based supercontinuum sources provide high spectral power and broad coverage in a small footprint which makes them interesting for in-situ open-path multispecies detection. Here, we demonstrate our recent results this application.
Mid-infrared supercontinuum sources can provide a broad spectral bandwidth in the molecular fingerprint region, making them very attractive for multispecies trace gas detection. We demonstrate our recent developments combining these with FTS.
