Abstract
The application of tunable diode lasers for in situ diagnostics in lam inar hydrocarbon diffusion flames is demonstrated. By the use of both direct-absorption and wavelength-modulation (second-derivative) techni ques, carbon monoxide concentrations and the local flame temperature a re determined for a laminar methane-air diffusion flame supported on a Wolfhard-Parker slot burner. In both cases the results are found to b e in excellent agreement with prior measurements of these quantities u sing both probe and optical techniques.
