Abstract
The use of electron beams for pumping dense gases made it possible to obtain lasing on atomic and molecular transitions in different spectral ranges and to develop high-power pulsed lasers. N.G. Basov and coworkers made a substantial contribution to the formation and advancement of this field. A brief review of the research on efficient elevated-pressure active media and high-power pulsed lasers utilising plasmas produced both by an electron beam and an electron-beam-controlled discharge is presented. These are excimer and exciplex lasers, lasers utilising atomic transitions in xenon and neon, an Ar —N2 mixture laser, a molecular nitrogen ion laser, and a high-pressure CO2 laser. Data obtained in the investigation of the radiation of rare-gas halide complexes are given.
