Description Concentration of free hydrogen atoms was measured by the two-photon absorption laser-induced fluoresence (TALIF) in an externally heated atomizer in a mixture of argon, hydrogen and oxygen at atmospheric pressure. Free hydrogen atoms were generated in a flame located at the end of a capillary that supplied O2 into the Ar - H2 mixture. The atomic hydrogen concentration in the order 1022 m-3 was found in the region around the flame. Optimal gas composition for atomic hydrogen production was found and an effect of gas flow on the atomic hydrogen distribution was observed.
