摘要

Measurements of the concentration of molecular hydrogen in high temperature reactive systems by use of Coherent anti-Stokes Raman Spectroscopy (CARS) is described. The theoretical analysis on the CARS line shapes is performed including the Doppler broadening and the collision narrowing effects in order to evaluate the dependence of CARS signal intensity on the temperature and the pressure of the system. The method is applied to the following two systems; the distribution of H//2 concentration in the hydrogen-air diffusion flame and the rotational relaxation rate of molecular hydrogen in the supersonic nozzle flow. It was noticed that the spatial resolution along the laser axis was very influential, and it was necessary to know the local temperature in the complex system as the former system.
