摘要： A gas laser, in particular an axial-flow CO2 gas laser, includes a resonator having a folded beam path in a first folding plane and in a second folding plane inclined at 45° thereto. At least one Z-fold of the beam path is provided in the first folding plane and at least one U-fold of the beam path is provided in the second folding plane.

摘要： A slab laser includes cooled, mutually parallel electrodes having a given thickness. The electrodes have flat surfaces facing each other and defining a discharge chamber therebetween for containing a gas to be pumped, and the electrodes have flat surfaces facing away from the discharge chamber. Each of the electrodes has a plurality of sections being spatially separated from one another over at least a portion of the given thickness of the respective electrode. The electrodes are supported in such a way that movements of the flat surfaces facing away from the discharge chamber being caused by thermal expansion are opposed by only a negligible mechanical resistance.
