Amplification and absorption in lasers utilizing 3p–3s neon transitions in the red part of the spectrum
The saturation fluxes, unsaturated gain, nonresonant loss factor, and stimulated transition cross sections were determined for electron-beam-pumped lasers utilizing the 3p[1/2]1–3s[3/2]1 (λ = 724.5 nm) and 3p[1/2]1–3s[3/2]2 (λ = 703 nm) neon transitions. The physical nature of the absorption in the active medium and its dependence on the specific pump power were analyzed.
