ABSTRACT OF THE INVENTION A device is disclosed for a CO2 power laser, the beam paths of which are disposed in a rectangle. The laser has a first intermediate corner flange and a first deflecting mirror in the first corner zone, an intermediate second corner flange and a second deflecting mirror in the second corner zone, a third intermediate corner flange and a third deflecting mirror in the third corner zone, and an end flange, an output mirror and a 180° total reflection mirror in the fourth corner zone. There is a gas pipeline between the first and the second intermediate corner flanges, a second gas pipeline between the second and third intermediate corner flanges, a third gas pipeline between the third intermediate corner flange and the end flange, and a fourth gas pipeline between the end flange and the first intermediate corner flange. There are HF pumping electrodes on the gas pipelines. The laser has a gas supply device for cooled gas, a gas draining device for heated gas, a heat exchange device for the gas, a gas pump working in the circuit and connected to the gas supply device and to the gas draining device, and a base device carrying the intermediate corner flanges and the end flange. In the first to fourth gas pipelines there is in each case a first to fourth through-flange which in each case sub-divides the associated gas pipeline into in each case two partial gas pipelines. The gas pump is provided in the area of intersection of the diagonals across the corner zones. The gas pump is a turbo radial fan. At least parts of the gas supply devices and gas drain devices are situated in a stellate disposition between the turbo radial blower and the intermediate corner flanges, through flanges and the end flange. The base device is a high table top in the cavity in which the partial paths extend. The turbo radial blower is at least indirectly flanged onto the table top.
