A high-voltage pumped gas laser has a gas-discharge path which is provided in a gas-proof chamber (1) between two electrodes which are arranged opposite, and an X-ray radiation source (10) for pre-ionising the gas located between the electrodes. For this purpose, the X-ray radiation is directed onto the gap between the electrodes. Suitable mirrors are provided in order to generate the laser radiation. In order to achieve a particularly effective result and to bring the X-ray radiation source (10) as close as possible to the gaps between the electrodes, the gas-discharge path consists of a plurality of electrode pair sections which are arranged distributed around a centre (8) in the form of a train of polygons, while the X-ray radiation source (10) is provided inside the polygon which is braced by the electrode pair sections, especially in the centre (8).
