NukW Harnessing Power
Nuferns commitment to high-power active fibers and fiber integration has enabled us to deliver a
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 and electronics mounting, 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. How would you like yours?

NuPOWER Laser & Amplifier Fibers
Nufern has developed world class Yb, Er:Yb, and Tm-doped fibers.
Our large mode area (LMA) fiber technology has been deployed in
hundreds of laser and amplifier systems since 2002. These fibers
have demonstrated unprecedented power
stability, narrow linewidth, extreme
brightness and conversion efficiency
not just at the beginning, but over a long
service lifetime.
Design Flexibility Remote mounting of pump diodes Separate electronics package Higher powers multi-kW available Available in multiple form factors
Optical Attributes High beam quality M
2
< 1.2 Long beam delivery up to 10 m High optical efficiency ~ 90% slope efficiency Narrow linewidth 7 GHz demonstrated Polarization Maintaining option
Example System
Rack-mounted configuration,
with commercial power supply,
integrated heat exchanger, and
4 m beam delivery.
