Abstract
An ignitor for a preionizing means of an excimer laser has an electrically conductive core which projects into the gas space of the laser and which is surrounded by a jacket of a fluoroplastic. The jacket is brought into sealing engagement with the wall of the laser gas space by means of a pressure sleeve via mating conical surfaces.
