Verfahren und Vorrichtung zur Erzeugung von Laserstrahlung hoher Leistung und guter Qualitaet

Process for the production of high power and high quality laser radiation, in particular for high- performance solid state lasers by which the radiation of several single beams (2a to 2c) generated in non-consecutive ray path sections (1a to 1c) is concentrated in a collecting device (3) to form a single output beam (4). In order to obtain that the beam quality of the high-performance output beam resulting from the individual beams is equal to the beam quality of the individual beams, the process involves the operation of a first laser device (5a) during a first period of time (t<-a), the operation of second laser device (5b) during a second period of time following the first period of time (t<-b)) and that the operating times (t<-a, t<-b) of the two laser devices (5a, 5b) or at least a further laser device (5c) alternate cyclically to obtain a temporally uninterrupted output beam (4), and that the resulting single beams (2a to 2c) occurring chronologically are concentrated in the same axis by the collecting device (3).
