PLMA-EYDF-20P/250-XPH, PM Er/Yb-Doped Double Clad Optical Fiber with Pedestal
Coherent proprietary rare earth doping technology is used to deliver Er/Yb co-doped fibers with industry-leading performance and reliability. This fiber features a 20 µm diameter core and a 250 µm diameter cladding with a 0.09 NA. The fiber design has been optimized to deliver high efficiency and suppressed 1 µm parasitic ASE, ensuring unmatched stability. The large core allows for shorter fiber lengths in amplifiers and laser systems, reducing the impact of non-linear effects. The NuCOAT fluoroacrylate coating ensures excellent beam quality preservation and extended operating life at the high power levels demanded by today’s industrial fiber laser applications.
