Commercial gas sensors based on quantum cascade laser (QCL) spectroscopy usually rely on a single measurement technique, such as the direct absorption approach, the photoacoustic method, or measuring the dispersion. While each method has its advantag

The present work reports on the first application of a ring-cavity-surface-emitting quantum-cascade laser (RCSE-QCL) for sensitive gas measurements. RCSE-QCLs are promising candidates for optical gas-sensing due to their single-mode, mode-hop-free an
