Abstract

A generation of atomic iodine via F atoms with their immediate injection to the supersonic COIL nozzle has been studied. Very high concentrations of I atoms were obtained in the laser cavity in the absence of O₂(¹Δg). Low values of small signal gain measured in the O₂(¹Δg) flow did not correspond to high efficiency of I generation. This was ascribed to O₂(¹Δg) quenching by DO₂· radical.
