At the upcoming Laser World of Photonics Conference in Munich, blue lasers expert, NUBURU, will be showcasing its 500-Watt 450-nm AO-500 industrial laser, bringing the power of blue light to deeper materials processing applications. Set to debut at the event, the new laser follows the 2017 introduction of the award-winning 150-Watt AO-150 laser by NUBURU.
Gold, aluminum, and copper are among the metals that absorb blue light much more than they do the infrared wavelengths of conventional industrial lasers. According to NUBURU, the physics of absorption provides blue lasers with the ability to efficiently process copper and other industrially important metals. For example, the AO-500 produces better quality copper welds at a higher speed than any alternative welding method.
According to NUBURU CEO Mark Zediker, 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, 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.
NUBURU will be showcasing the capabilities of the AO-500 at the Laser World of Photonics Germany (Hall B3 booth 103) in Munich from June 24 to 27.
