Broadband Mid-Infrared Dual Comb Spectroscopy with Comb-Tooth Resolution and High Signal-To-Noise Ratio

Not Accessible

Your library or personal account may give you access


We demonstrate a mid-infrared dual-comb spectrometer that can measure comb-tooth resolved spectra across an octave of bandwidth in the mid-infrared from 2.6—5.2 µm with kHz frequency precision and a signal-to-noise ratio up to 5,000:1.
