介绍了计算机产生的相干反斯托克斯拉曼光谱(CARS)光谱，它是测量燃烧环境中的温度和组分浓度所必需的。根据玻尔兹曼振动-旋转态分布和正常拉曼截面，编制了控制N_2和CO产生CARS的三阶非线性电极化率程序。有限的泵浦激光宽度和仪器效应可以用适当的卷积来解释。给出了用这些理论光谱测量火焰温度(N_2)和少数组分浓度(CO)的实例。
Computer-generated coherent anti-Stokes Raman spectroscopy (CARS) spectra, necessary for temperature and species concentration measurements in combustion environments, are presented. The third-order, non-linear electric susceptibility governing CARS generation from N2and CO has been programmed in terms of a Boltzmann distribution of vibration-rotation states and the normal Raman cross-sections. Finite pump laser widths and instrumental effects are accounted for by appropriate convolutions. Examples of flame temperature (N2) and minority species concentration (CO) measurements using these theoretical spectra are presented.
