Abstract
Abstract Abstract of the Disclosure: High energy laser of the TEA type, including a discharge tube having an optical axis of the laser and a gas discharge space formed therein, at least two main electrodes being spaced apart and oppo-sitely disposed in the discharge tube and extended parallel to the optical axis, excitation being carried out by condenser discharge being free of arcs and as homogeneous as possible in the gas dis-charge space between the electrodes, at least one of the main electrodes having a mushroom-shaped cross section with a mushroom-shaped stem for current conduction and a mushroom-shaped hat for current distribution and being extended into the gas discharge space, ant at least one rod-shaped auxiliary electrode being disposed parallel to the optical axis and at a given sparkover distance from one of the electrodes, for pre-ionization of the gas discharge space, the at least one auxiliary electrode having an inner conductor and a dielectric surrounding the inner conductor. LAG/amm.
