ABSTRACT:
The aim of the invention is to obtain a laser system with the highest possible power that operates as stably as possible. This object is achieved in the case of a laser system by the laser radiation field passing through at least two laser-active solid bodies of identical material disposed one following the other in the direction of its beam axis, by the pumping radiation guide being formed in such a way that it feeds into each of the solid bodies the first partial radiation field via one end face and the second partial radiation field via the other end face and by the pumping radiation guide being formed in such a way that a pumping power fed into each of the at least two solid bodies by the two partial radiation fields can be adjusted in such a way that the effects on the laser radiation field of thermal lenses produced by the pumping power in each of the at least two solid bodies are substantially identical.
