Device description
The series of high power fiber laser described in this operating manual
was developed particularly for welding and cutting applications on met-
als and metal alloys. Depending on the configuration, the type and num-
ber of connections and operating elements as well as the power of the
laser can vary. The precise information can be found in the supplied
technical data.
3.1
Functional principle
The laser radiation is generated in these laser modules, which are inte-
grated in the laser. Every laser module can be understood as an inde-
pendent laser.
The output power of the laser modules can differ depending on the
type. The number of modules is determined by the nominal output
power of the laser.
The laser modules require direct voltage to generate the laser radiation.
The direct voltage is generated by the laser power supply, which is inte-
grated into the laser.
The radiation generated in the laser modules is guided by the associ-
ated fibers into the combiner module, where they are combined into a
single fiber. The fiber from the combiner module is spliced to the feed-
ing fiber in the splice box; the laser radiation is fed here into the feeding
fiber. Via the feeding fiber, the laser radiation enters the external weld-
ing optics, which are specific to the system owner and focus the laser
radiation on the material processing point.
Depending on the selected configuration, the feeding fibers may differ
in core diameter and length.
