Project Description

(18 + 1) x1 Pump and Signal Combiner

DK Photonics’ (18+1) x1 Multimode Pump and Signal Combiner is designed for high power applications. It features exceptional optical characteristics. These devices can combine N pump lasers and 1 signal channel into one fiber and create a high power pump laser source, 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 Pump and Signal 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.
