We present the study of the emission and discharge characteristics in a nitrogen laser pumped by the transverse discharge from the generator with inductive energy storage and SOS-diodes. It is shown, that in the N2-NF2 mixture it is possible to form the emission pulses at the wavelength of 337.1 nm, consisting of two pulses spaced from each other by 12 ns time gap and by 25 ns interval between the pulse maxima. Radiation energy of 23 mJ per pulse was obtained.
