HIGH BRIGHTNESS, FIBER DELIVEREDBLUE LASERS FOR METALS PROCESSING

The NUBURU BL-F series are high brightness, blue lasers thatprocess metals better and more efficiently than IR or green lasers andintegrate with standard scanning systems. This enables them to service
a wide range of welding, additive manufacturing, and other materials
processing applications in batteries, e-mobility and consumer electronics.

eMobility/Energy Storage

The high brightness of the NUBURU BL-F series, combined withscan head delivery, offers an ideal laser for metal processing due to thehigh absorption of blue light by metals: including 13x for copper and3x for aluminum. Reducing the excess heat input compared to infraredlasers enables spatter-free and defect free welds with the highest possible
mechanical and electrical performance.
With available output powers from 125W to 1kW, these blue lasers canpower mass production solutions for <1mm copper and aluminum welds
which require a large process window and demand extremely high yields.
