title: Spatially resolved optical Stark-modulation spectroscopy in flames.
abstract: This Letter describes the application of spatially resolved optical Stark-modulation spectroscopy for making point-absorption measurements in combustion environments by monitoring transitions between electronic energy levels. The technique is demonstrated in a study of atomic sodium aspirated into a flame.
