Electrode for gas laser comprises structured surface consisting of bundle of wires and/or rods having regular or irregular quadrangular cross-section

摘要

The electrode has a surface (14) which is structured in the direction of a discharge zone (12). The structure of the electrode surface consists at least partially of the ends (24) of multiple wires and/or rods (18) arranged in a bundle and having a regular or irregular quadrangular or triangular cross-section. The wires or rods are pressed, clamped, stuck or soldered into electrodes (10).
