Lumentum Unveils Higher Output Power - 200 Watt - ST2 Pump Laser

New Laser Leverages Established, Highly-Reliable Pump Platform; Accelerates Development of 2 kW+ Fiber Lasers   

Milpitas, Calif., and San Francisco, Calif., January 30, 2017 – Lumentum Holdings Inc. (“Lumentum”) added today a 200 W output power fiber-coupled pump laser module – the ST2 – to its portfolio. This new diode laser leverages the industry-proven track record of the Lumentum high-brightness pump laser family. The ST2 also supports the “build-your-own” kilowatt (kW) laser market. Available today in volume quantities, the ST2 diode laser is showcased in Lumentum booth #1917 – South Hall at SPIE Photonics West from January 31 – February 2, 2017, at Moscone Center in San Francisco, Calif.  

“With its first generation of high-brightness pump lasers, Lumentum took a market leadership role in driving the ’build-your-own‘ kW laser market ecosystem,” said Dr. Tomoko Ohtsuki, product line manager, Industrial Diode Lasers. “By designing in the ST2 200 W pump laser, customers can easily scale their fiber laser powers to 2 kW or higher, which is important due to the increasing adoption of multi-kilowatt lasers in machine tools where processing time and high-volume throughput are critical.” 

Powered by Lumentum’s next-generation diode laser chip, combined with optical and mechanical design innovations to achieve ultra-low optical loss and power management, the ST2 delivers 200 W of power within 0.15 numerical aperture of a 135 µm core fiber. The ST2 builds on the Lumentum reputation for industry-best reliability. The product has been rigorously tested for endurance and power stability to withstand prolonged use in manufacturing applications.
