Eye Safe Laser & Amplifier Fibers

Nufern has developed world class Er:Yb co-doped fibers. This technology has enabled fibers with > 40% efficiency at 1550 nm. Optical fibers produced with these compositions have been designed with large mode area (LMA) technology to generate high peak power pulses while reducing the deleterious non-linear effects often encountered in short pulse applications. Eye-safe output at 2 µm wavelengths is also possible with Nufern’s highly efficient Tm-doped fibers.
