II-VI SUWTECH launches high-power fiber-laser pump module

In booth 2323 at the SPIE Photonics West 2015 event in San Francisco (10-12 February), II-VI SUWTECH of Shanghai, China (part of II-VI Inc of Saxonburg, PA, USA) is introducing a high-power fiber-coupled diode pump module platform that will offer scalability for different power levels up to 300W with different emitter and fiber configurations (105μm and 200μm fiber core). With more emitters integrated, the single-emitter-based platform offers increased brightness.

The high-brightness pump enables fiber-laser manufacturers to generate higher pump power levels using fewer modules, allowing them to increase pump block efficiency, design more compact pump configurations, and simplify their packaging, says the firm. A novel optical scheme delivers light into the fiber with high coupling efficiency, and a controlled under-filled numerical aperture (NA) - along with a cladding mode stripping feature - allows increased reliability and reduced losses at the combiner. A compact housing aids thermal management. Integrated design and fewer components enable high volume with high manufacturing efficiency with high consistency in module-to-module performance, claims the firm.

II-VI also offers unique 300W per port Nx1 high-power combiners with the modules together that can handle 300W per input port. High-power Nx1 multimode combiners enable high-efficiency combining of multiple high-power pump sources into a single output fiber. Up to 31 input ports are available, corresponding to multi-kilowatt power handling capability. All II-VI Photonics combiners conform to stringent environmental and mechanical standards to give high reliability and long lifetime for all field applications, the firm adds.
