Kinetic model of an N2 — H2 laser based on the 3s → 2p transition in the lithium-like nitrogen ion

A time-dependent self-consistent kinetic model is developed for a laser emitting as a result of the 3s →2p transition in the lithium-like nitrogen ion (λ = 26.5 nm) in an N₂ — H₂ mixture excited by a hard-ionisation source. The results of a numerical simulation demonstrate that such a mixture can emit radiation in the superradiant regime. The optimal lasing conditions are identified and a study is reported of the influence of uncertainty in the plasma-chemical reaction constants.
