Abstract: In a process for the quantitative detection of a given gas and in a device for the quantitative detection of a given gas, a gas sample (3), which may contain the given gas as a component, is irradiated with a diode laser (1) operating in a single mode and free of mode jumps, the wavelength of which being continuously tuned by varying the laser control current. The laser control current is varied by superimposing a sinus modulation current of a predetermined frequency to a periodically varied d.c. component so that a laser wavelength range is scanned in the area of the absorption line of the given gas. The intensity of the laser radiation after passing through the gas sample is measured by means of a detector. The d.c. component of the detector signal and the second harmonic of the detector signal corresponding to the doubled frequency of the sinus modulation current are determined.
