Combustion gas measurements using tunable laser absorption spectroscopy. Interim report

Technical Report ·
OSTI ID:5506327
Applications of tunable infrared diode lasers for combustion gas measurements are described. The diode laser serves as a source of narrow-linewidth infrared radiation whose wavelength can be rapidly modulated to perform fast, high-resolution absorption spectroscopy. Measurements of fully resolved vibration-rotation lines in the fundamental band of CO are used to infer temperature, CO species concentrations and CO collisions halfwidths in the post-flame gases of a flat flame burner. The feasibility of diode laser measurements in fluctuating and particle-laden combustion flows is also demonstrated.
