Research output: Chapter in Book/Report/Conference proceedingConference contribution


A phase sensitive signal detection scheme for molecular spectroscopy based on chirped laser dispersion spectroscopy (CLaDS) is presented. We demonstrate application to sensitive remote sensing of trace gases using a 5.2 μm quantum cascade laser.
