Abstract
In order to improve a laser system comprising several laser radiation sources, each of which generates laser radiation which is coupled into a first end of a respective optical single-mode fiber, wherein all optical single-mode fibers form a fiber bundle and have second ends lying at a fiber bundle end, the laser radiation exiting from the second ends and thereby forming a total laser radiation field, and further comprising an optical transformation means which transforms the total laser radiation field onto an object, such that a focal point with a highest possible power per area and per solid angle can be generated therewith, it is proposed that the optical transformation means comprise a collimating element which collimates the laser radiation exiting divergently from each individual second end of the single-mode fibers and forms a collimated radiation bundle therefrom, and that the optical transformation means comprise a focusing element which images the collimated radiation bundle as a whole onto a focal point.
