II-VI Incorporated - II-VI Suwtech will introduce its new high power fiber laser pump module at Laser World of Photonics 2015 in Munich, Germany.
II-VI Suwtech's high power fiber-coupled diode pump module platform offers the scalability of output powers up to 300W with different emitter and fiber configurations (105µm fiber core for power levels less than 200W and 200µm for more than 200W). With the integrated innovative design, this single emitter based platform delivers increased brightness.
This new platform has been designed to address kilowatt class fiber laser applications. The novel optical schematic couples the diode beam into the fiber with high efficiency and the controlled NA. A cladding mode stripping feature allows customers to reduce optical loss on fiber splicing and increase overall reliability. The high output power/brightness enables fiber laser manufacturers to generate higher power levels using fewer pump modules to increase electrical-to-optical conversion efficiency and to design pump configuration with a compact footprint. Integrated design and fewer components ensure high efficiency on volume manufacturing, module performance and extended product lifetime.
II-VI Suwtech 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.
