SLD Laser, a company commercializing visible laser-based light sources and blue laser products, has demonstrated ultra-compact, high-power, high-brightness, fiber-coupled blue laser modules for materials processing applications including copper welding for battery production for electric vehicles and consumer electronic devices, as well as 3D printing.

SLD’s blue laser light modules feature up to 12 times the absorption, processing quality and speed compared to infrared laser technology. This technology produces superior results in copper, aluminum, stainless steel, as well as other metals such as nickel, gold, titanium, and silver that are commonly used for plating, other thin metal processes and 3D printing.

SLD’s blue laser module technology is ultra-compact, with a form factor roughly the size of a credit card, and delivers more than 20 watts from a 100 micron transport fiber. The technology is modular and can be power-scaled and aggregated with optical fibers into higher power systems to deliver hundreds of watts from high brightness delivery fibers less than 600 microns diameter.

SLD’s blue laser modules feature the company’s proprietary and patented Semipolar GaN laser diode technology.
