Abstract: The method of coherent anti-Stokes Raman scattering (CARS) was used in shock-wave diagnostics. CARS spectra were obtained, for the first time, for nitrogen heated in the equilibrium zone of a shock wave in the temperature range 1.6–3.2 kK. The experimental data were analyzed using a model which took into account collisional transfer in the Q band of N₂ and the effects of two-photon Raman saturation.
