    Key Feature

    • Wavelength:~444nm.
    • Power Options: Available output powers from 125W to 1kW.
    • High Brightness: Exceptional brightness for efficient metal processing ,more efficiently than IR or green lasers and integrate with standard scanning systems.
    • Scan Head Delivery: The high brightness o f BL series, combined with scanhead delivery, offers an ideal laser for metal processing due to the high absorption of blue light by metals: including 13x for copper and 3x for aluminum compared to infrared lasers.
    • Reduced Heat Input: Minimizes excess heat, leading to spatter-free and defect-free welds with the highest possible mechanical and electrical performance.
    • Mass Production Ready: Ideal for high-yield, mass production solutions for copper and aluminum welds <1mm .
    • Large Process Window: Accommodates a wide range of processing parameters for diverse applications.
    • Compact Footprint: Simplifies integration.
    • Direct Interface Capability: Can directly interface with standard scanners.
    • High Reliability: All semiconductor laser design ensures reliability and long lifetime.
    • Cost-Effective: Lower cost of ownership compared to fiber and solid-state lasers.
    • Spatter-Free Welding: Achieves spatter-free and defect-free conduction mode welds.
    • Higher Weld Joint Densification: Produces denser weld joints for enhanced performance.

    Applications

    • Batteries and energy storage.
    • E-mobility.
    • Consumer electronics.
    • Interconnects.
    • Electronics packaging.
    • 3D metal printing (powder bed fusion and wire feed).
