Coherent anti-Stokes Raman scattering (CARS) is a coherent optical variant of the inelastic light scattering process known as the Raman effect. CARS spectroscopy possesses the universality of Raman spectroscopy but with greatly enhanced sensitivity. It is insensitive to background luminescence, can be configured to allow remote measurements, has excellent temporal and spatial resolution, and can provide detailed information on both the chemical composition and physical state of gas, liquid, and solid samples. Because of these desirable attributes CARS has become an important optical diagnostic method, in particular for characterizing combustion media, plasmas, and chemically reacting mixtures. This article provides a brief introduction and overview of such applications of CARS, with a particular emphasis on the last of these.
