Nuburu to show highest power Blue Laser in Munich


500W 450nm industrial laser brings the power of blue light to deeper materials processing applications.

Colorado-based laser innovator Nuburu will be bringing the world's highest-brightness high-power blue laser to Europe at this summer's Laser World of Photonics (LWP) Conference in Munich June 24th to 27th.

The 500W 450nm AO-500 industrial laser brings the power of blue light to deeper materials processing applications. It follows the company's 2017 introduction of the award-winning 150W AO-150.

Gold, aluminum, and copper are among the metals that absorb blue light much more than they do the infrared wavelengths of conventional industrial lasers. "The physics of absorption provides blue lasers with the ability to efficiently process copper and other industrially important metals," said Nuburu's co-founder Jean-Michel Pelaprat. "For example, the AO-500 produces better quality copper welds at a higher speed than any alternative welding method."

High power is only the beginning of the story, because the efficiency and quality of materials processing applications are driven by power density. Increasing power density by a factor of four increases weld depth more than one-and-a-half times and increases the weld speed three to four times. "The AO-500's beam parameter product is less than 30-mm-mrad," said Nuburu CEO Mark Zediker, "enabling rapid defect-free copper welding, and even welding dissimilar metals with minimal formation of undesirable intermetallics in the joint."

Nuburu produced the world's first industrial-class blue laser with an innovative design that individually aligns each of the output beams from a multi-diode packaged chip. Sixteen of these diode packages are efficiently integrated in the AO-500 - a design approach that offers the highest industry-leading brightness. Early adopters are already leveraging the advantages of high power and brightness in applications such as battery fabrication, automotive component production, e-mobility device fabrication, and electronic packaging.
