Fiber combiner

Fiber combiner is a critical passive optical component in high-power fiber laser systems. It is typically fabricated using the Tapered Fused Bundle (TFB) technique, where multiple input fibers are bundled, heated, tapered, and then fused to a single output fiber.

The core function of a fiber combiner is to efficiently couple multiple pump or signal lights into a single output fiber, making it essential for power scaling in fiber lasers and amplifiers
