Overview

Idealphotonics®Yb85-6/125-PM fibers are very highly doped single mode fibers for low power fiber laser and amplifier applications. The fibers offer excellent single-mode beam quality for 1um applications and combine high pump absorption with low photodarkening loss. They are ideal fibers for low-cost marking lasers and pumping sources.Yb85-6/125-PM fibers are available as double cladding (Yb85-6/125-DC) and double cladding polarization maintaining (Yb85-6/125-PM-DC) fibers.
