Definitions

  • the pumping light emitted by the pumping light source 34 is to be coupled into a total of four foci in, for example, four fibers 68 of a light guide, then it is possible and advantageous to divide this pumping light into four Spaces spaced apart, for example, in the pumping light source 34 facing away from the surface of Kollim ists- and Focusing lens 68 to integrate.
  • the collimating and focusing lens 68 does not focus only on one focus, but focuses the light emitted from the pump light source 34 on four foci designated F 4 through F 7 in FIG. This makes it possible to divide the pumping light emitted by the pumping light source 34 into a plurality of partial beams 60.1 to 60.4 and individual fibers 68 of a
