KernsOptic (Shenzhen Kanghao Technology Co., Ltd.) makes custom passive components for high-power fiber lasers and amplifiers, including fused N×1 and (N+1)×1 pump combiners, PM pump and signal combiners, mode field adapters (MFA), cladding light strippers (CLS), and pump protectors. Configurations cover 800–1000 nm pumps, 105/125, 200/220, and 20/400 fibers, with custom double-clad geometries. Engineering confirms the final configuration before quotation.

Choosing a pump-combining architecture? Compare N x 1 and (6+1) x 1 pump combiners, then use the pump combiner selection guide to organize the parameters for review.

ENGINEERING NOTES

Configuration details

Key choices to confirm before selecting a model or requesting engineering review.

Which pump combiner configurations does KernsOptic offer?

N×1 pump combiners in 3×1 and 7×1, and PM pump and signal combiners in (1+1)×1, (2+1)×1 and (6+1)×1. Custom fiber combinations are reviewed case by case.

Which component goes where in a fiber laser chain?

Pump protectors on the diode lines, the pump combiner into the active double-clad fiber, a mode field adapter where seed and signal fibers differ in core size, and a cladding light stripper after the active fiber to remove residual pump light.

Are samples free?

No. Prototypes are paid and typical build lead time is 4–10 weeks after the configuration is confirmed.
