1. The Role of Multimode Pump Combiner
What is a Multimode Pump Combiner?
A multimode pump combiner is a sophisticated optical device that facilitates the combination of multiple pump lasers into a single fiber. This technology provides an efficient means of achieving higher output power from a laser system while ensuring exceptional beam quality.
Working Principle
The multimode pump combiner works on the principle of combining multiple laser diodes or fiber lasers into a common multimode fiber. Each pump laser input is aligned and coupled with the multimode fiber, allowing their outputs to merge coherently. This coherent combination results in a significant boost to the overall output power.
