摘要

The discharge channel for a gas laser has a dielectric channel wall (18,20) and at least two opposing electrodes (38) defining a discharge space (22) for the laser gas flow between them. The channel wall (18,20) incorporates at least one metal core (40) which is screened from the discharge space via a dielectric. The metal core (40) is fitted through the channel wall (18,20), to lie between a glass plate (19) and a ceramic plate (21) applied to its inside surface and enclosed by a dielectric cover (68). The gap between the cover and the metal core (40) is filled by a binder mass which is elastically or plastically deformable and which exhibits no HF dielectric losses.
