Claim:
1. A laser arrangement having a converter for generating converted laser output radiation and having a pumping source which delivers pumping radiation for the converter and comprising: a plurality of laser diodes generating the pumping radiation, wherein the pumping source comprises beam-forming optics for forming laser beams delivered from emitters into the pumping radiation, wherein a converted output radiation of the converter is fed via a flexible light guide to a working treatment head delivering the converted output radiation, wherein a flexible light guide is a converter fiber of the converter, wherein the converter fiber is accommodated in an interior of a sleeve-like sheathing through which a cooling medium can flow, and beam-forming optics including an optical element acting as a collimator lens for the formation of a parallel or essentially parallel beam and, following the beam forming optics with the optical element in a beam path, a second optical element provided in the treatment head acts as a focusing lens for forming a focused output and/or processing beam, wherein a first optical device and a second optical device are each constituted by at least one plate spreader with a plurality of plates following one another at their surface sides, the plates of the first optical device are orientated with their surface sides normal to a first axis (Y axis) and the plates of the second optical device are orientated with their surface sides normal to a third axis (Z axis).
