In order to prevent the formation of large size turbulences in an axial gas laser, there is provided an inlet, respectively an outlet jet, uniformly distributed at the pipe periphery in a gas inlet area, respectively a gas outlet area, in the energizing path (1). An annular inlet nozzle (52) is formed by the continuous contour of the pipe wall and the continuous end portion of an extension pipe (50) which penetrates axially into the pipe (1). Thereby, the formation of large size turbulences in the cross-section of the pipe (1) with the optical axis (A) is substantially prevented. In order to avoid consequential effects of the conditions prevailing in the gas outlet area in the pipe (1), there are created on the outlet side conditions which are similar to those prevailing in the inlet side. |
