What is Ytterbium?
Ytterbium is a rare-earth element widely used as a dopant in optical fibers and laser materials to create an active gain medium. Ytterbium-doped fibers are particularly suited to generating and amplifying high-power laser signals, typically around the 1 µm wavelength range.
Ytterbium offers a broad absorption and emission range and can be efficiently pumped with commercially available laser diodes. These properties make ytterbium-doped fibers attractive for high-power fiber lasers and amplifiers, including systems requiring high optical efficiency, good beam quality, and robust operation.
key properties of Ytterbium
Efficient energy conversion
Ytterbium can efficiently convert pump light into laser light, making it well suited to high-power fiber lasers and amplifiers.
Broad operating range
Its absorption and emission characteristics support operation across a relatively broad wavelength range around 1 µm.
High-power capability
Ytterbium-doped fibers can provide high optical gain and power while maintaining the advantages of fiber-based laser architectures.
