SLD Laser of Goleta, CA, USA (a spin-off from LED lighting firm Soraa Inc that is commercializing visible laser-based light sources and blue laser products for automotive, industrial, specialty lighting and display applications) has demonstrated compact, high-power, high-brightness, fiber-coupled blue laser modules for materials processing applications including copper welding for battery production for electric vehicles (EVs) and consumer electronic devices, as well as 3D printing. At Laser World of Photonics 2019 in Munich, Germany (24–27 June), the firm is debuting the blue laser module technology, and also demonstrating its UL and IEC safety-certified high-luminance LaserLight-SMD and LaserLight-Fiber products.

“SLD’s blue laser light modules feature up to 12 times the absorption, processing quality and speed compared to infrared laser technology,” reckons says president, chief operating officer & co-founder Dr James Raring. “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,” he adds.

SLD’s blue laser light output is also highly absorptive in non-metals and organics, and therefore is suitable for marking, engraving and cutting of these materials. Moreover, for biomedical applications, it exhibits more than ten times absorption in blood hemoglobin and melanin in skin than infrared lasers, enabling next-generation solutions in dermatology and surgery.

SLD says that its blue laser module is ultra-compact (with a form factor roughly the size of a credit card) and delivers over 20W from a 100μm 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 600μm diameter. The modules feature the firm’s proprietary and patented Semipolar GaN laser diode technology, with highly efficient and reliable operation to enable system integrators and application development teams to configure solutions for a wide variety of applications, and to get to market quickly.

Also at Laser World of Photonics, SLD is showcasing its LaserLight product line. The firm has recently initiated production of the UL and IEC safety-certified LaserLight-SMD and LaserLight-Fiber products, including the recently demonstrated fiber-coupled SMD and SkyBeam (the first 12,000 lumen LaserLight spotlight for outdoor lighting applications based on the SMD). LaserLight products won the Technical Innovation Award at May’s LightFair International trade fair in Philadelphia, PA.

“We have recently entered production for our two first LaserLight product lines into the automotive and specialty lighting markets, delivering up to 10 times higher visibility and safety than can be achieved with LEDs, and replacing older legacy lighting that contains mercury,” says chief marketing officer & co-founder Dr Paul Rudy. “LaserLight products serve a myriad of applications such as automotive headlights, portable handheld flashlights, drones, off-road light bars, and professional applications in search and rescue, marine, avionics, architecture, and entertainment,” he adds. “We are thrilled to now take the next step, and introduce the blue laser module technology for emerging industrial materials processing and biomedical applications.”

SLD Laser is hosting meetings at Laser World of Photonics in Hall B2 Booth 125-4 of the USA Pavilion.
