When metal welding fails due to spatter, cracks, or poor bonding, manufacturers lose time and money. For materials like copper and aluminum, even traditional lasers struggle to deliver clean, strong welds. Is there a better solution?
Red-blue hybrid lasers combine the energy density of fiber lasers with the absorption efficiency of blue lasers to deliver cleaner, stronger, and more stable welds on challenging metals like copper and aluminum.
While conventional fiber lasers face limits with highly reflective materials, hybrid solutions open new possibilities. In this article, we explore how Vivlaser’s 200W blue + 1000W fiber hybrid laser system is solving some of the toughest welding challenges in modern manufacturing.
Why is hybrid laser welding better for copper and aluminum?
Copper and aluminum reflect infrared light, which leads to energy loss and unstable welding. This makes high-speed, high-quality welding difficult.
A hybrid laser system1 blends high-absorption blue light (450nm) with high-power fiber light (1080nm) to achieve deeper penetration, better fusion, and more stable welding processes.
Understanding material interaction with different wavelengths
| Material | IR Absorption (1080nm) | Blue Light Absorption (450nm) |
|---|---|---|
| Copper | Very low | High |
| Aluminum | Moderate | Moderate |
Blue lasers improve energy coupling on copper and aluminum. But their limited power restricts industrial usage. Combining them with fiber lasers fills this gap, offering both energy density and absorption control.
