New series of high power fibre lasers

ROFIN has launched a new series of high powered fibre lasers. The new FL Series offers two models, the FL x75 and FL 010, with output powers of 750 and 1,000 Watts respectively. The beam quality from the new lasers can be coupled with fibre optics of between 50 μ m and 600 μ m in diameter, equivalent to beam quality of 2.5 to 30mm x mrad.

In addition, the Rofin FL 010 S offers a fibre laser solution with single mode beam quality of 0.4mm x mrad and 1,000 Watt output power. Small parts can be welded with low thermal distortion and minimal heat affected zones, and steel or aluminium can be joined with welding depths of several millimetres.

The beam quality allows the efficient use of ‘dynamic beam’ scanner systems, enabling 2D and 3D geometries to be processed. The optional beam switch and energy share modules make it possible for a single laser to be used in up to four individual work cells, providing maximum use of the beam source. These features support improved cycle times and productivity while minimising the initial capital equipment costs. FL Series lasers are designed to be easily integrated to new or existing production work-cells. The lasers are designed for low-maintenance operation and long-term performance. Unlike the traditional concept, where the laser beam moves repeatedly between the air and the laser active medium, the beam of a fibre laser does not leave the fibre optics before reaching the processing optics (single mode) or the beam switch (multi mode). This ‘all-in-glass’ technology also reduces the risk of optical contamination and eliminates changes in beam quality.
