Dual-pump dual-broadband coherent anti-Stokes Raman scattering in reacting flows

Summary, in English

A dual-pump, dual-broadband coherent anti-Stokes Raman scattering system for simultaneous measurements of temperature and concentrations of N-2, O-2, and CO2 in reacting flows is demonstrated. In this system pure rotational transitions of N-2-O-2 and rovibrational transitions of N-2-CO2 are probed simultaneously with two narrowband pump beams, a broadband pump beam, and a broadband Stokes beam. The main advantage of this technique is that it permits accurate temperature measurements at both low and high temperatures as well as concentration measurements of three molecules.
