Paper Abstract

At Sandia Laboratories a number of non-linear optical spectroscopies are being applied to combustion-related problems. A principal long term goal is to obtain the temperature and concentration of major species in highly luminous, particulate-laden combustion environments. With the use of pulsed lasers and crossed beam geometries, these techniques can provide excellent temporal, spatial, and species resolution. In addition, these methods can generate relatively strong signals with high rejection of background radiation. Thus, non-linear spectroscopy promises to provide valuable information in hostile environments where spontaneous Raman scattering is of limited utility or not feasible. Recently the detection of stimulated Raman gain/loss signals produced by a single (10 ns) laser pulse in gaseous methane and nitrogen has been demonstrated. Implications of these preliminary results on combustion research are discussed.
