Overview
LIEKKITM (6+1)x1 multimode pump and signal combiners are designed to combine power from six multimode laser diodes with a signal feed. These combiners are used in high power fiber amplifier and laser applications across industrial, military, medical, and communications sectors. They ensure efficient power transfer while maintaining brightness.

Specifications
The LIEKKITM combiners are available in various configurations:

• Combiner-6/125DC: Core size 105 µm, Cladding size 125 µm, Core NA 0.151
• Combiner-10/125DC: Core size 105 µm, Cladding size 125 µm, Core NA 0.151
• Combiner-20/125DC: Core size 105 µm, Cladding size 125 µm, Core NA 0.151
• Combiner-20/400DC: Core size 200 µm, Cladding size 220 µm, Core NA 0.22

All models have a pigtail length of > 0.5 m and operate within a signal wavelength range of 1000 - 1100 nm and a pump wavelength range of 900 - 1000 nm. They offer > 90% pump transmission and > 80% signal transmission.

Performance
Each combiner supports a maximum input power per fiber of 8 W (100 W for Combiner-20/400DC). They maintain a return loss and directivity of > 40 dB. Operating temperatures range from 0°C to +30°C, with storage temperatures from -5°C to +70°C.

Applications and Benefits
These combiners are ideal for cladding pumped fiber amplifiers and lasers. They are all-fiber, highly reliable, and preserve modal content, ensuring high performance and reliability.
