  Technical advantages   Download PDF

 

  • Scalable in power up to 10 Cw
  • Single wave length design
  • High efficiency of the beam shaping
    and focusing
  • Confocal compact design
  • Large working distance
  • Small divergence in focus
  • Homogenous power distribution
    in focus
  • Unsensitive against back reflections

 

  • Cw- or pulse operation possible
  • Hollow optical axis
  • 2D welding path needs no orientation
    of the head
  • Coaxial feeding of additional materials
    like powder or filler wire
  • Large heat interaction zone above
    the TCP
  • Perfectly suitable for optical pumping
    of solid state lasers
 

Typical applications

 


All material processing methods involving additional materials profit from the laser design
and especially all filler wire and powder deposition welding procedures like 2D brazing of
thin car body blanks as well as the repairment of turbine blades as well as coating
procedures and all heat conduction welding, heat treatment and thermal treatment like
remelting, hardening, brazing, polishing dechambering and cleaning but also laser
assisted reforming or drawing of wire profit also tremendously from the advantages
constructive properties of the ringfocus laser.
