“…The traditional method to produce O 2 (a 1 Δ g ) is through gas-liquid chemical generator, and recent trend is using electric discharge. The discharge technology used in exciting CO 2 lasers has been extended to producing singlet delta oxygen, including DC discharge [1] , micro-wave discharge [2] and RF discharge [3~5] . Carroll [4] demonstrated the continuous-wave laser on the 1315nm by energy transfer from O 2 (a 1 Δ g ) in RF discharge.…”

The pulsed discharge in oxygen and its mixtures to produce singlet delta oxygen has been studied experimentally at gas pressure of 30~ 936mBar. As singlet sigma state of oxygen O 2 (b 1 Σ g + ) and atomic oxygen O have great influence on the yield of singlet delta oxygen O 2 (a 1 Δ g ), the visible spectrum of O 2 (b 1 Σ g + ) at 762nm and O at 778nm have been measured, and the effects of argon, helium and carbon monoxide have been discussed. The electric stability was better in O 2 -He than in O 2 -Ar mixtures, while it could be increased quickly with a small amount of CO. In O 2 -He mixtures more oxygen were decomposed than in O 2 -Ar mixtures, while adding CO the decomposition was reduced, the amount of atomic oxygen was decreased, and the O 2 (b 1 Σ g + ) was increased comparatively. The time-resolved spectrum of the plasma has also been measured. The life-time of atomic oxygen was longer than O 2 (b 1 Σ g + )'s, and it could be shorten with argon.
