Photolytic generator of excited oxygen O2(a1Δg)

An analysis is made of the kinetics of physical processes in an ozone-oxygen mixture exposed to ultraviolet radiation. It is concluded that an excited-oxygen generator can be developed having a relatively high efficiency and ensuring a high O₂(a¹Δ_g) content. This can be used to obtain lasing due to the 5²P_1/2→5²P_3/2 spin-orbit transition in an iodine atom (λ = 1315 nm) by energy transfer from O₂(a¹Δ_g).
