Abstract
Lasing energy of 10 mJ was obtained for the first time under nitrogen pumping by a pulsed inductive discharge with a pulsed power higher than 1 MW. The lasing pulse length of the inductive nitrogen laser created was (8.5 ± 0.5) ns (FWHM). The lasing was obtained at two wavelengths of 337.1 and 357.7 nm. The lasing beam had a ring cross section with a diameter of about 33 mm and a width of about 2 mm.
