Abstract
Improving the spectral acquisition rate of broadband mid-infrared spectroscopy promises further advancements of molecular science and technology. This paper demonstrates the fastest continuous broadband mid-infrared spectrometer running at 80 MSpectra s⁻¹ by implementing a wavelength-swept time-stretch spectroscopy technique. The proof-of-concept experiment shows broadband absorption spectroscopy of phenylacetylene with a signal-to-noise ratio of 85 without averaging and a shot-to-shot fluctuation of 1.3%.
