Laser action in gas mixtures of different gases with NF3 and SF6 pumped by a volume diffuse discharge formed in nonuniform electric field by run-away electrons (REP DD) is studied. Efficient lasing on HF(DF) and nitrogen molecules was demonstrated. Laser action on atomic transitions of Ne (λ = 585,3 nm, Ar (λ = 750,3 nm), F (λ = 712,8 и 731,1 nm), and on XeF* molecules (λ = 351 and 353 nm) was studied, as well. It was shown that the volume discharge initiated by run-away electrons (REP DD) in gas mixtures with SF6 is a source for efficient excitation of gas lasers on HF, DF, и N2 molecules.
