ABSTRACT:
In a laser arrangement comprising at least one laser medium for producing a laser emission, a laser resonator having a beam path with a length of at least 20 cm and with at least one end mirror, the beam path within the laser resonator is formed at least partly by free-beam optics. A resonator element arranged in the beam path has at least two optical surfaces as surfaces interacting with the radiation led via the beam path, these optical surfaces being rigidly connected to one another and being adjustable together in the beam path in such a way that, on tilting by an angle error, they achieve substantially the same effect on the guidance of the beam path but with opposite sign, so that mutual compensation of tilt errors takes place.
