Abstract
Several new laser-based detection methods for use in combustion diagnostics are described. Spatially resolved saturated absorption spectroscopy and optical Stark modulation spectroscopy provide two techniques for obtaining point resolution in absorption measurements; these methods are demonstrated in studies of atomic sodium aspirated into a flame. Resonant multiphoton optogalvanic spectroscopy can be used to observe radicals in flames that are extremely difficult to detect with conventional optical techniques; studies of atomic hydrogen and atomic oxygen in flames are presented.
