Abstract
A CO2 power laser has beam paths in gas pipelines disposed in a rectangle with a plurality of corner flanges, and an end flange, and through flange that subdivide each gas pipeline. Partial paths of a gas supply device and partial paths of a gas drain device are situated in a star-shaped device between a turbo radial blower and the corner, end and through flanges. The star-shaped device has cavities in which the gas supply and gas drain paths extend.

In a CO2 power laser device having beam paths disposed in a rectangle and a plurality of corner zones, and comprising:
- a first corner zone with a first intermediate corner flange that holds in position a first deflecting mirror,
- a second corner zone with a second intermediate corner flange that holds in position a second deflecting mirror,
- a third corner zone with a third intermediate corner flange that holds in position a third deflecting mirror,
- a fourth corner zone with an end flange that holds in position an output mirror and a 180 degree total reflection mirror,
- a first gas pipeline between said first and said second intermediate corner flanges,
- a second gas pipeline between said second and said third intermediate corner flanges,
- a third gas pipeline between said third intermediate corner flange and said end flange,
- a fourth gas pipeline between said end flange and said first intermediate corner flange,
- HF pumping electrodes connected to said gas pipelines for exciting gas that flows in said gas pipelines,
- a gas supply device for carrying cooled gas to said gas pipelines,
- a gas drain device for carrying heated gas from said gas pipelines,
- heat exchange devices for cooling gas that flows in said gas pipelines, a gas pump connected to said gas supply device and to said gas draining device for pumping gas through said gas pipelines,
- a base device carrying said intermediate corner flanges and said end flange,
- the improvement wherein:
- (a) a through-flange is connected to each of said gas pipelines and sub-divides the gas pipeline to which it is connected into two partial gas pipelines,
- (b) said gas pipelines form a right-angled rectangle,
- (c) said gas pump is provided approximately at the intersection of diagonals across said corner zones,
- (d) at least partial paths of said gas supply device and at least partial paths of said gas drain device are situated in a star-shaped device between said turbo-radial blower and said intermediate corner flanges, through-flanges and end flange, and
- (e) said gas pump is a turbo-radial blower that has an axis at a right angle to said star-shaped device, wherein said axis substantially traverses said area of intersection of said diagonals,
- (f) said star-shaped device has cavities in which said paths of said gas supply device and said gas drain device extend,
- (g) wherein there are provided four partial paths for the supply of gas and four partial paths for gas dispersal, some partial paths extending to said intermediate corner flanges and said end flange and other partial paths extending to said through-flanges, and
- (h) said turbo-radial blower is at least indirectly flanged onto said stellate device.
