LuxBlue® High Power Blue Diode Laser Source

Challenge

Conventional infrared lasers fall short when processing reflective, non-ferrous metals. Their low absorption rates—often below 5%—lead to energy inefficiencies, inconsistent welds, excessive spatter, and thermal damage to surrounding materials. Industries such as EVs, aerospace, and electronics require a more effective laser solution for working with copper and aluminium components.

Solution

The YESWEHAVE High Power Blue Diode Laser series is engineered specifically to address these limitations. With a wavelength of 450 nm, it achieves more than 50% absorption in non-ferrous materials, enabling:

• Clean and reliable welds on highly reflective surfaces

• Reduced spatter and heat-affected zones

• Enhanced process stability in high-precision applications

• A compact footprint, ideal for integration in space-constrained production lines

• Scalable power options from 200 W to 4000 W, adaptable to diverse manufacturing needs

Use Cases of Blue Diode Lasers

Blue Diode Lasers are designed to meet the needs of modern, precision-driven industries. Their unique properties make them ideal for diverse, high-performance applications.

• Battery tab welding: Enables fast, clean joins in copper and aluminium battery tabs for EVs and energy storage units, improving durability and electrical conductivity.

• Copper busbar processing: Delivers high-absorption precision when welding or cutting copper busbars used in automotive and aerospace power systems.

• Micro-welding of electronics: Supports fine, detailed welding for delicate components in PCBs and consumer electronics without damaging adjacent circuitry.

• Reflective metal additive manufacturing: Ideal for processing metallic powders like aluminium and copper, ensuring better melt pool control in 3D printing systems.

• Precision cutting for enclosures: Produces smooth, accurate cuts in thin aluminium housings for telecoms, batteries, and industrial enclosures.

• Medical device fabrication: Maintains material integrity when welding intricate stainless steel or titanium parts, where minimal heat input is essential.

Advantages of Blue Diode Lasers

The YESWEHAVE High Power Blue Diode Laser series delivers more than just cutting-edge performance. It helps manufacturers optimise quality, efficiency, and uptime across operations.

• Superior metal absorption: Copper and aluminium absorb blue light at 450 nm significantly more, ensuring efficient energy transfer during processing.

• Cleaner weld results: It minimises spatter and excess melt, resulting in cleaner seams and less post-processing work.

• Low thermal impact: Smaller heat-affected zones protect adjacent components and reduce the risk of warping or microcracks.

• Compact, modular design: It is built for flexible integration into existing production lines, even where space is limited.

• Stable performance at scale: It maintains consistent weld and cut quality across large production volumes and varying material conditions.

• Cost-efficient operation: Optimised energy use and fewer reworks help drive down overall manufacturing costs.

• High reliability: Robust diode design supports extended uptime, even in intensive, round-the-clock operations.
