<p>A laser resonator, in particular for carbon dionide lasers, comprises two final resonator mirrors having active material between two fully reflecting final mirror surfaces, which form an unstable resonator cavity, and at least a third fully reflecting mirror surface which reflects the laser beam before the latter is outcoupled through the outcoupling opening in the resonator. To obtain a laser with lower outcoupling characteristic and/or improved beam quality, at least one stable resonator cavity is provided, in addition to the unstable resonator cavity, between the two final mirrors, and said stable resonator cavity is made of the same active material as the third mirror surface as the surface of one of the two final mirrors with the surface of the other final mirror.</p> |
