Abstract
An electrode for pulsed gas lasers consisting substantially of tungsten and copper has a long life. With such an electrode contaminations of the laser gas and of the windows are largely obviated, even in long-time operation. An electrode suitable also for fluoride-containing laser gases consists essentially of an alloy containing copper, aluminium and nickel.
