Abstract

The results of the experimental investigation into a nitrogen laser pumped by a longitudinal discharge in which nitrogen is replaced by air are presented. The fabrication of an experimental sample of such a laser is reported. The laser is excited by a pulse generator with voltage inversion in storage capacitors, which charges the discharge capacitor connected to a two-section discharge tube with an inner diameter of 6.7–17 mm and a length of one section of 100–217 mm. It is shown that, at an air pressure of 7–9 mm Hg and its pumping through the discharge tube, the laser can operate with a pulse repetition rate of up to 100 Hz and provide a radiation pulse energy of 0.27–1.9 mJ at a wavelength of 337.1 nm at a duration of 4 to 13.5 ns.
