NukW: Kilowatt Laser Amplifier Platform

NukW — Harnessing Power

Nufern's commitment to the development of state of the art high-power active fibers, requisite components and fiber integration has enabled us to deliver a dynamic kilowatt-level optical amplifier platform suitable for beam combining applications.

NukW systems provide superior optical performance including single-mode beam quality, very high optical efficiency, and narrow linewidth. With remote diode pumping, separate electronics mounting co, counter or bi-directionally pumped optical cavities, and beam delivery up to 10 meters, the integration possibilities for a NukW system offer unmatched flexibility.

Delivered as a complete turnkey unit ready for immediate installation and use, the NukW amplifier is enabling the next generation of high energy laser development.
