In a laser device designed according to the gas transport or convection principle, the division into parts with different functions is replaced by complete integration of the different functions. According to the invention which covers a tangential flow laser, the gas circulation system which consists of a rotor with radial blades arranged normal to the direction of flow of the laser gas almost, completely fills the casing. The rotor blades on one side are adjacent to the cooled wall of the casing and on the, other side are adjacent to the excitation system which extends along the wall of the casing.
