Abstract:Production of singlet delta oxygen (SO) by a dc glow discharge in flowing O2 : Ar mixtures has been investigated. SO concentrations have been measured with dilution of oxygen up to O2 : Ar = 5 : 95 at a pressure up to 14 Torr and specific power load in the discharge up to 50 J mmol−1. The largest relative SO concentrations achieved in experiments exceeded 9%. This is sufficient to obtain population inversion and laser gain in the oxygen–iodine medium.It was found that for the mixtures with large Ar content str… Show more
