Abstract

Highly sensitive atomic detection can be achieved from the combination of CW laser excitation and saturated absorption. We have used CW saturated fluorescence methods for single-atom detection and for background rejection in flames. With the development of CW tunable UV dye lasers dye lasers the methods can be applied to the detection of most metallic elements. Because the photodetector can be physically isolated from the laser excited volume, these methods are applicable to elemental analysis with all types of atomizers, and for diagnosis of combustion products, flow processes, and plasmas.
