The new Coherent HighLight FL4000CSM-ARM fiber 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 comprising dissimilar materials, such as copper and aluminum, and foil stacks that require precise control.

The dual beam output (center beam surrounded by a ring beam) allows welding of thin, conductive materials. The center beam has extremely high brightness (nominal BPP 0.6), allowing a small spot size that provides very high laser intensity and minimizes material heating. The ring beam offers a preheating effect. Together, they produce a melt pool with improved stability, which increases weld consistency.
