Mid infra-red absorption spectrometry based on continuous-wave distributed feedback (DFB) quantum cascade laser (QCL) is more and more widely used for trace gas detection and pollution monitoring. The main advantages of this technique are high sensit

The same quantum cascade laser spectrometer working around 9 μm was used in both continuous-wave and pulsed modes to compare their own characteristics. The laser emitting in continuous-wave mode was mainly used to study some spectroscopic parameters
