LMA-YDF-20/400-HP-M (2kW)
Matched Yb-doped Double-Clad Optical Fiber

Product image of LMA-YDF-20/400-HP-M (2kW) Matched Yb-doped Double-Clad Optical Fiber

NuMKW fibers eliminate TMI and SRS for power scaling to >3kW in existing laser architectures. With 1.5kW, 2kW, and 3kW options, these fibers feature unmatched performance that benefit many applications, including lowest photodarkening, SRS, TMI and the highest beam quality. NuMKW fibers reduce the $/W value and eliminate the need to design and develop expensive solutions. NuMKW fibers come with matched fiber designs for passive components and beam delivery.
