Ytterbium-doped fiber (DF1100) is a ytterbium-doped single-mode (SM) fiber with high doping levels for use in low-power fiber lasers and amplified spontaneous emission (ASE) light sources. The DF1100 is designed for core pumping around 915nm or 980nm. High absorption rates allow short gain lengths for femtosecond mode-locked ring lasers or preamplifiers.

The emission spectrum of the fiber can be tuned by changing the length of the fiber, and emission from 1030nm to 1100nm can be achieved through the DF1100.
