Abstract: Laser-optical sensors are applied whenever sensitive, selective and fast in-situ gas analysis is required. This contribution illustrates the performance of selected near- and mid-infrared spectrometers based on tunable diode-lasers. Applications of lead-salt diode-lasers for NO2 and CH4 sensing, of antimonide lasers for CH4 and HCHO sensing in the 3-4 µm range and a near-infrared gas sensor for CO2 based on a room temperature 2 µm Indium-Phosphide laser will be presented and spectrometer performance will be discussed.
