Abstract: The present invention relates to a ring-down spectrometry apparatus in absorption saturation condition, for measuring the concentration of a gas through a measurement of the spectrum of a molecular transition of said gas. The apparatus includes a laser source, an adjuster for varying the wavelength of said radiation emitted by said laser, and a resonant cavity. A photodetector is adapted to detect an electromagnetic radiation beam and is adapted to generate a decay signal. An electronic circuit receives the signal from the photodetector and is adapted to convert it to a processor. A processor is adapted to receive said decay signal from the photodetector and perform interpolation to obtain a concentration of said gas.
