Doped Fiber Pump Combiner,also call active pump combiner, is build by coupling pump fiber power directly into doped fiber(say Yb-doped, or Er/Yb doped ect), the signal input fiber is passive fiber, and the splice point is put inside combiner.
Doped Fiber Pump Combiner,also call active pump combiner, is build by coupling pump fiber power directly into doped fiber(say Yb-doped, or Er/Yb doped ect), the signal input fiber is passive fiber, and the splice point is put inside combiner. Normally customer splices doped fiber with combiner output passive fiber, which will cause backward scattering. Active combiner makes customer no need to splice again outside combiner and will get very good isolation between backward light and pump lasers.
The structure has 2 advantages compare with normal combiner:
1. Customer only need splice one time with doped fiber at combiner signal side.
2. The coupling region is behind splice point, the isolation(backward signal to pump) is much lower than normal passive combiner, so that protect pump LD burning.
DK Photonics’ Doped Fiber Pump Combiner(N+1)x1 offer efficient power transfer for high power applications like direct diode materials processing and pump cascading with a maximum conservation of brightness. The Multimode Pump and Signal 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 Doped Fiber Pump Combiner including (2+1)x1,(6+1)x1 and so on.Pump fiber,singal fiber and output fiber type and the configuration can be customized.If you do not see a Pump and Signal Combiner from the standard configurations that meets your needs, we welcome the opportunity to review your desired specification and quote a custom Pump and Signal Combiner. Requests for custom pump fiber,singal fiber,output fiber type and the configuration,the handling power or other specific needs will be readily addressed. DK Photonics can respond to custom requirements with short lead times.
