HIGH BRIGHTNESS, FREE SPACE OUTPUT
BLUE LASERS FOR METALS PROCESSING

The NUBURU BL™ series are high brightness, blue lasers that process
metals better and more efficiently than IR or green lasers and integrate withstandard scanning systems. This enables them to service a wide range ofwelding, additive manufacturing, and other materials processing applications
in batteries, e-mobility and consumer electronics.

Consumer Electronics

The high brightness of the NUBURU BL series, combined with scanhead delivery, offers an ideal laser for metal processing due to the highabsorption of blue light by metals: including 13x for copper and 3x foraluminum. Reducing the excess heat input compared to infrared lasers
enables spatter-free and defect free welds with the highest possible
mechanical and electrical performance.
With available output powers from 125W to 250W, these blue lasers can power
mass production solutions for <500micron copper and aluminum welds which
require a large process window and demand extremely high yields.
