ABSTRACT:
A laser (2e), particularly a CO.sub.2 gas laser, is described which has a stimulating path supported on a common carrier (74e) and sub-divided into a plurality of partial paths. The partial paths (46) extend solely radially in relation to a common center (6e) and are connected to one another optically in pairs via deflecting mirrors (10e) and optical connecting paths (12e) between the deflecting mirrors (10e) at their radially outer ends. The laser (2e) is of very compact construction, has a high output and functions very reliably. Heat expansions of component of the resonator beam extend substantially radially of the center (6e) and do not result in maladjustment of the resonator beam.
