Coherent anti-Stokes Raman scattering (CARS) spectroscopy has been used to investigate cryogenic liquid oxygen/gaseous methane (LOX/CH4) flames on a medium-size test facility at a pressure of 0.24 MPa and mass flow of 0.025 kg/s. Single-shot, broadband CARS spectra with simultaneous detection of the Q-branches of hydrogen and water molecules were recorded with good signal-to-noise ratio. Temperature was deduced from the H2 and H2O CARS profiles. The spatial temperature distribution in a comparatively harsh environment has been measured successfully. The measurements took place in the windowed combustion chamber of the DLR M3 test facility, aiming to provide data for validation of rocket combustor modeling.
