Abstract Lasers on the second positive nitrogen system (the C{sup 3{Pi}}{sub u}-B{sup 3{Pi}}{sub g} electronic band, {lambda}=337.1 and 357.7 nm) are studied. Mixtures of nitrogen with electronegative gases (SF{sub 6} and NF{sub 3}) are pumped by transverse and longitudinal discharges. The amplitude-time and spectral characteristics of a laser pumped from capacitive and inductive energy storage units are measured. The output energies of the laser pumped by a transverse discharge from a capacitive and inductive storage units are 17 and 18.4 mJ, respectively. It is shown that the mean output energy in N{sub 2}-NF{sub 3} mixtures continues to increase at higher pulse repetition rates than in nitrogen. Under the pumping by a transverse discharge, two-peak 357.7-nm lasing with a total pulse duration of >40 ns is achieved. It is established that adding SF{sub 6} to the mixture enhances the output power of a longitudinal-discharge-pumped nitrogen laser. (lasers)
