Abstract: | The lasing on the electronic transitions of xenon and neon is studied. It is demonstrated that plasma-cathode accelerators
serve as effective sources for the pumping of low-threshold lasers (W < 100 W/cm3). The laser energy in xenon at the wavelength λ = 1.73 μm is 5 J at an efficiency of 2%, and the laser energy in neon at
the wavelengths λ = 585.3 nm is 0.5 J at an efficiency of 0.3%. The repetitively pulsed mode of the xenon and neon lasers
carried out at a repetition rate of 50 Hz. The radiation energy of a wide-aperture laser with an active volume of 600 l is
100 (0) J for a wavelength of 1.73 (2.03) μm at an efficiency of 2% (1%).
