摘要： A method of and an apparatus for quantitative analysis in accordance with CARS wherein a first system filled with a material to be measured and a second system filled with a reference material of known concentration are disposed in series; first laser light of a first frequency for excitation is applied to these systems together with second laser light having frequency of wide band width; light passed through these two systems, respectively, is applied to a spectrograph provided with, a multi-channel detector; and quantitative analysis for the material to be measured is effected on the basis of a ratio of intensity between the signal outputs generated in respective different channels of the multi-channel detector and corresponding to the material to be measured and to the reference material respectively. Furthermore, anti-Stokes' light emitted between rotational levels of hydrogen is utilized in the case of quantitative analysis of hydrogen.
