DK Photonics 3x1 multimode pump combiner combines 3 multimode lasers power to create a high power output with consigned fibers. It features exceptional optical characteristics. The output fiber can be transmitting energy fiber as the energy synthesis, it also can be no core fiber or LMA double clad fiber, which people can splice with match doped LMA double cladding fiber.
DK Photonics’ Multimode Pump Combiners offer efficient power transfer for high power applications like direct diode materials processing and pump cascading with a maximum conservation of brightness. The Multimode Combiners can be designed to meet a wide range of power handling configurations, number of input fibers and adaptation to different fiber types.
We can produce the Nx1 pump combiner including 2x1,3x1,4x1,7x1,19x1,37x1 pump combiner and so on. Pump fiber, output fiber type and the configuration(Nx1) can be customized, with power handling per multimode port of, 10W, 25W,50W, 100W(200W or higher can be customized).
