SM-YDF-8/130-9M Double-Clad Fiber SM-YDF-8/125-9M
Coherent/Nufern’s ninth-generation NuGEN9 active fibers use advanced glass compositions and fiber designs, precisely matched to corresponding passive fibers for excellent splice compatibility and low splice loss. SM-YDF-8/130-9M is a ytterbium-doped single-mode active double-clad fiber with an 8um core, 130um cladding and core numerical aperture 0.095. Applications include military, industrial and medical systems. Optimized glass composition provides higher absorption with excellent photodarkening performance. A 100kpsi proof-test level provides industrial long-term reliability. Nufern’s NuCOAT-FA coating performs well in dry-heat and damp-heat environments, maintains output beam quality and extends fiber service life.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift.
