Demonstration of mid-IR gas sensing with frequency-swept Fabry-Perot cavity quantum cascade laser

Chin, Sanghoon; Mitev, Valentin; Giraud, Eliane; Maulini, Richard; Hempel, Frank; Lang, Norbert; Wiese, Mathias; Zimmermann, Henrik; Boiko, Dmitri L. (2022-09-16)

We demonstrate an innovative approach for a mid-IR gas sensing spectroscopy with a cost-effective commercial Fabry-Perot cavity quantum cascade laser. Using transient blue-chirped emission of such a laser, the spectral ...
Utilization of a frequency-swept Fabry-Perot cavity quantum cascade laser for an innovative mid-IR spectrometer

Chin, Sanghoon; Mitev, Valentin; Giraud, Eliane; Maulini, Richard; Hempel, Frank; Lang, Norbert; Wiese, Mathias; Zimmermann, Henrik; Boiko, Dmitri L. (2022-05-07)

We present an innovative approach for a mid-IR spectrometer comprising a commercial Fabry-Perot cavity quantum cascade laser. Utilization of the transient blue-chirped emission of such a laser the spectral fingerprint of ...
