Fourier-Transform Infrared Spectroscopy with Near-Infrared Light

Name: Work Video:
Duration: 3 min 30 s
Description: Nonlinear interferometers using correlated photon pairs allow mid-infrared spectroscopy with near-infrared detection. In our work, we combine nonlinear interferom- etry with a measurement scheme and analysis in analogy to classical Fourier-transform spectroscopy, which enhances the spectroscopic performance.
