[en] The idea of creating an artificially ionized region in the atmosphere by means of high-frequency pulsed breakdown in intersecting beams of radio waves was described by Gurevich. This idea was given further treatment by Borisov et al., where a large number of questions related to the electron kinetics in the discharge region were studied. Since many fast electrons are produced during the breakdown time, various electronic states of the molecules must be excited and subsequently emit radiation. Laboratory experiments succeeded in observing the stimulated UV radiation in the second positive system of nitrogen (λ = 3,371 angstrom) produced in a microwave discharge. An important property of the radiation emitted in free space when breakdown occurs in intersecting radio beams is the presence of a propagating ionization front and the associated excitation of electronic states. The purpose of the present work is to describe studies of the generation of UV radiation by a propagating ionization front suited to conditions in the terrestrial atmosphere. The possibility is discussed of creating an atmospheric laser using the second positive system of nitrogen in connection with high-frequency pulsed breakdown of air in intersecting beams of radio waves. A calculation is given of the intensity of the stimulated radiation and the magnitude of the effect is estimated
