摘要： 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.

摘要： In order to so improve an aerodynamic window device for a laser which isolates the laser cavity pressure and comprises a jet nozzle and a diffuser arranged opposite the jet nozzle for generating a free jet extending from the jet nozzle to the diffuser and covering an exit aperture, that variable setting of the pressure level in the laser cavity is possible, it is proposed that a side wall (80) of the diffuser (72) which faces away from the laser cavity (34) be adjustable, at least in sections thereof, relative to a free jet direction (68).
