Abstract

A clear need exists within the combustion research community for methods capable of making sensitive spatially resolved measurements of species concentrations. Several new crossed-laser-beam techniques for making such measurements are outlined here, including the first application of saturated absorption spectroscopy for making point absorption measurements and the first application of spatially resolved optical Stark modulation spectroscopy for monitoring electronic transitions in atoms.
