quattroXX - multi-focal beam shaping optics for multi-kW lasers

Laser beam shaping by splitting laser energy and focusing in multiple focuses by quattroXX optics is developed for material processing by multi-kW fiber lasers or fiber-coupled lasers: welding, cladding, brazing. Focusing in 4 separate focuses with variable energy balance and geometrical layouts (square, rhomb, line) is flexible tool to optimize process conditions by doughnut-like spots, pre- and post-heating of processed area to reduce spatter and bubbles. Properties:

  • lossless energy re-distribution
  • TEM00 or multimode lasers
  • wide spectrum
  • high resistance to multi-kW CW or pulse lasers
  • reduced thermal focus shift.

As afocal optical system the quattroXX optics locates between collimator and focusing lens, in case of scanning optics before the scanner. Due to low sensitivity to misalignments and compact design the quattroXX can be quickly, easily and simply integrated in already existing process heads.
