4X1 Pump Combiner


DK Photonics’ 4X1 Multimode Pump Combiner is designed for high power applications. It features exceptional optical characteristics. These devices can be used to combine the power from several multimode laser diodes, delivering the combined power for applications in industrial, military, medical and telecommunications markets. It has a heat sink package and a hole for temperature monitoring.

DK Photonics’ Multimode 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 pump combiner including 2x1,3x1,4x1,7x1,19x1,37x1,and so on.Pump fiber,output fiber type and the configuration can be customized.If you do not see a pump combiner from the standard configurations that meets your needs, we welcome the opportunity to review your desired specification and quote a custom pump combiner. Requests for custom pump 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.
