II-VI Suwtech showcasing high-power fiber-laser pump module at Laser World of Photonics

In hall B1 (booth 403) at Laser World of Photonics 2015 in Munich, Germany (22-25 June), II-VI Suwtech of Shanghai, China – a subsidiary of engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA – is showcasing its new high-power fiber-coupled diode pump module platform that 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 an integrated design, the single-emitter-based platform delivers increased brightness, says the firm.

The 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 controlled NA (numerical aperture). A cladding-mode-stripping feature allows users 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 a pump configuration with a compact footprint, says the firm.

The integrated design and fewer components ensure highly efficient volume manufacturing, module performance and extended product lifetime, it adds.

Together with the modules, II-VI Suwtech also offers unique 300W per port Nx1 high-power combiners 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. II-VI notes that all its photonics combiners conform to stringent environmental and mechanical standards to give high reliability and long lifetime for all field applications.
