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 50μm
and 600μm 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.
