Long-wave mid-infrared cavity-enhanced frequency comb spectroscopy of cold, complex molecules
Negar Baradaran, Dominik Charczun, Tanay Nambiar +4
We report the development of a new instrument for cavity-enhanced absorption spectroscopy of the fundamental rovibrational transitions of molecules in the long-wave mid-infrared (L…

Direct frequency comb cavity ring-down spectroscopy: Enhancing Sensitivity and Precision
Romain Dubroeucq, Dominik Charczun, Piotr MasÅowski +1
We present a novel approach to cavity ring-down spectroscopy utilizing an optical frequency comb as the direct probe of the Fabry-Perot cavity, coupled with a time-resolved Fourier…
