The beam quality from this new series of lasers, available from Laser Resources 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 laser offered by Laser Resources has the option of a fibre laser solution with single mode beam quality of typically 0.4mm x mrad and 1000 watt output power.
The FL Series Lasers provide the optimum solution to a wide range of applications. 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 millimeters. The beam quality of the lasers 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 on the lasers make it possible for a single laser to be used in up to four individual work cells providing maximum utilization of the beam source. These features support improved cycle times of the lasers and productivity whilst minimising the initial capital equipment costs. FL Series lasers are designed to be easily integrated to new or existing production work-cells.
Based upon 30years of experience within the industrial laser world this new technology is 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 reduces the risk of optical contamination and eliminates changes in beam quality. In terms of laser technology, fibre lasers are considered to have enormous potential for future development and will further support the diverse requirements of customers involved in high power material processing applications.
