FL4000CSM-ARM fiber laser for automotive applications

The new Coherent HighLight FL4000CSM-ARM fiber laser builds on the success of Coherent HighLight ARM fiber laser series already qualified for automotive applications. This new laser enables more advanced welding capabilities for high thermal conductivity metals, and aligns to welding requirements for e-mobility, energy storage, and general electrical interconnects consisting of dissimilar materials, such as copper and aluminum, and foil stacks that require precise control.

This new technology represents a significant improvement in simplicity, and overcomes the limitations of other joining technologies.

The Coherent HighLight FL4000CSM-ARM has been developed at the recently expanded “Center of Excellence for Fiber Lasers” in Tampere, Finland, and is available with an output power of 4 kW (1.5 kW center beam, 2.5 kW ring beam). As with other Coherent Adjustable Ring Mode lasers, power in the center and ring beams can be independently varied and modulated. The CSM-ARM is supplied with a 15 m length process fiber, making it easy to integrate in virtually any production environment, and is compatible with the standard process heads from Coherent and other manufacturers.
