An X-ray preioniser with an electron beam energy density of 0.1 J cm{sup -2} based on a high-voltage (20 - 40 kV) low-pressure glow discharge is developed for repetitively pulsed gas lasers. The electron concentration in the CO{sub 2} - N{sub 2} - He mixture as a function of the voltage across the preioniser is calculated for titanium and other foils. The preioniser can be operated both in a single-pulse regime and at pulse repetition rates ranging up to hundreds of Hertz. A specific energy yield of 51 J L{sup -1} is achieved in the X-ray preionised pulsed CO{sub 2} atmospheric-pressure laser. This preioniser was shown to be efficient for other active media (CO and excimer lasers), which opens up new opportunities for the development of repetitively pulsed gas lasers. (lasers)
