Abstract
The absolute concentration of atomic oxygen in atmospheric pressure hydrogen/air flame has been measured using Intracavity Laser Spectroscopy based on a dye laser pumped by an argon-ion laser. Absorptions at the highly forbidden transitions at 630.030 and 636.380 nm were observed at an equivalent optical length of up to 10 km. The relatively low intensity of the dye laser avoids photochemical interferences that are inherent to some other methods for detecting atomic oxygen. Detection sensitivity is about 6 X 1014 atom/cm3 and can be improved with better flame and laser stabilization.
