Abstract
A device for simultaneously processing a circumference of a workpiece includes a plurality of laser-lens modules and a waveguide. The modules each include a diode laser and a lens system and is configured to emit a laser beam radially in a shared radiation plane. The waveguide includes a lower part and an upper part that together form a cavity enclosing the radiation plane. The laser-lens modules are configured so that the laser is reflected repeatedly between a bottom surface and a cover surface and propagates in an unaffected manner within the radiation plane so as to form a beam spot that strikes the workpiece with a homogeneous energy distribution. The beam spot has a height based on a distance between the surfaces and a width based on a divergence angle in the radiation plane and a distance of the module from the workpiece surface.
