Gas laser
First Claim
1. An electrically excited gas laser of circular cross section perpendicular to the direction of beam propagation, including:
- an excitation chamber bounded by two concentric tube walls which serve simultaneously as electrodes for the gas discharge, and the outer tube wall having, on its inside, cavities in the form of slots disposed side-by-side, which are open toward the excitation chamber.

Abstract
Gas laser of circular cross section perpendicular to the direction of beam propagation, having an optical resonator. The laser has, for continuous or modulated continuous beam operation, a tube as the inner electrode (2), which is connected to a high-frequency voltage source. The outer electrode (4) likewise comprises a tube which is disposed coaxially with the inner electrode (2). Between the two electrodes (2, 4) is the annular excitation chamber (3). The tube wall serving as outer electrode (4) is provided with slot-like cavities (1) which are open toward the excitation chamber (3) and serve for the cooling of the gas therein.
