The results of investigation of an electric discharge XeCl laser with active region apertures 8 x 11, 10 x 15, and 15 x 15 cm are presented. The preionisation of the Ne - Xe - HCl working mixture was performed by soft X-rays and a low-current electron beam, which provided the initial concentration n{sub 0} of electrons in the gas from 10{sup 6} to 2 x 10{sup 13} cm{sup -3}. For n{sub 0} < 10{sup 12} cm{sup -3}, the homogeneity of the initial electron concentration and of an electric field in the discharge gap have a considerable effect on the homogeneity of the volume discharge and output characteristics of the laser. For n{sub 0} {>=} 10{sup 12} cm{sup -3}, a homogeneous volume discharge is ignited and is stable if the inhomogeneity of the electric field in the discharge gap does not exceed 10%. A storage capacitor charged to double the voltage of the quasi-stationary discharge operation is sufficient for discharge formation. It is shown that an improvement of the volume discharge homogeneity and a decrease in the size of the discharge chamber make it possible to increase the efficiency of a wide-aperture XeCl laser.
