Abstract
In order to improve a high-frequency excited gas laser with longitudinal flow, comprising a discharge channel having laser gas flowing therethrough in a direction of flow and high-frequency electrodes arranged on both sides of the discharge channel for generating a high-frequency discharge transversely to the direction of flow, such that a high output can be achieved with this laser in a manner which is, constructionally, as simple as possible and that its design is, at the same time, as compact as possible, it is suggested that the discharge channel comprise a plurality of channel elements, the channel axes of which are aligned parallel to one another in the direction of flow, that the channel elements be arranged beside or next to one another in a direction of installation transverse to the direction of flow and that the channel elements have a cross section having a greater extension in a first cross direction at right angles to the direction of flow than in a second cross direction extending at right angles to the first cross direction and to the direction of flow.
