Project Description

(2 + 1) x 1 Pump and PM Signal Combiner

DK Photonics’ (2+1) ×1 Multimode Pump and PM 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 PM 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.

We can produce Pump and PM Signal Combiner including (2+1) x1, (6+1) x1, (18+1) x1and so on. Pump fiber, signal 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 meet your needs, we welcome the opportunity to review your desired specification and quote a custom Pump and Signal Combiner. Requests for custom pump fiber, signal 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.
