摘要：
A method and devices for preionizing the main discharge gas volume of a gas discharge laser are described. The method and devices provide a preionizing discharge to the main gas discharge volume from above or below the main gas discharge volume. In combination with a shielding arrangement which reduces the spread of the preionization discharge other than to the main gas discharge volume, the exposure of other laser components and gas volumes to said preionization discharge is thereby minimized.
