PRODUCT DESCRIPTION
1. STN Series Blue Lasers
1.1 STN Series Fiber Coupled Blue Lasers
High brightness, fiber delivered blue lasers for metals processing
The STN Series Fiber Coupled Blue Lasers are high brightness blue lasers that process metals better and more efficiently than IR or green lasers and integrate 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. This series combined with scan head delivery, offers an ideal laser for metal processing due to the high absorption of blue light by metals: including 13x for copper and 3x for aluminum. 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 1kW, these blue lasers can power mass production solutions for <1mm copper and aluminum welds which require a large process window and demand extremely high yields.
