Optical saturation effects in intracavity Faraday modulation spectroscopy (INFAMOS)

We report on the observation of saturation effects in Intracavity Faraday Modulation Spectroscopy (INFAMOS). A quantum cascade laser operating at ∼5.3 μm is used to probe the 2Π3/2 and 2Π1/2 R(3.5) transitions in the fundamental band of nitric oxide. With average intracavity intensities up to 450 W...

description We report on the observation of saturation effects in Intracavity Faraday Modulation Spectroscopy (INFAMOS). A quantum cascade laser operating at ∼5.3 μm is used to probe the 2Π3/2 and 2Π1/2 R(3.5) transitions in the fundamental band of nitric oxide. With average intracavity intensities up to 450 W cm−2, the saturation of these molecular transitions is observed up to a total pressure of ∼240 Torr. The experimental data are interpreted by incorporating saturation into a model for the INFAMOS line shape in the homogeneously broadened limit.
