Fiber Pump Combiner

A passive optical device prepared on the basis of tapered fused fiber bundle. It peels off the coating layer of a bundle of optical fibers, then arranges them together in a certain way, heats them at high temperature to melt them, and at the same time stretches the optical fiber bundles in the opposite direction, and the heated area of the optical fibers melts into a tapered fused fiber bundle. Fiber pump combiners can increase the strength and energy density of optical fibers to achieve more efficient and precise operation and measurement, and can be used in optical communication, medical, industrial and scientific fields.
