Dual-pump CARS temperature and major species concentration measurements in counter-flow methane flames using narrowband pump and broadband Stokes lasers

Dual-pump coherent anti-Stokes Raman scattering (CARS) is used to measure temperature and species profiles in representative non-premixed and partially-premixed CH 4/O 2/N 2 flames. A new laser system has been developed to generate a tunable single-frequency beam for the second pump beam in the dual...
