Gas laser having a beam path folded in several planes

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.
