Abstract

Laser action is obtained on the $3p^{\prime }\left[1/2\right]0–3s^{\prime }{\left[1/2\right]}_1^{°}$ transition in Ne of λ = 585.3 nm by pumping dense Ne–H₂ and Ne–He–Ar mixtures (P = 0.2 − 3 atm) with an electron beam (j_max = 40 A/cm², τ_beam = 80 nsec). Inversion occurs because of the removal of the lower active state by the Penning reactions of Ne with H₂ and Ar. The total output energy is about 2 mJ; the output energy density is about 10⁻⁵ J/cm³ for 0.1% lasing efficiency estimated from the calculated energy input.
