Extra Large Mode Area Fibers

Nufern is expanding its broad range of active triple clad fibers with Extra Large Mode Area (XLMA) fibers using Heraeus’ proprietary process for making large core doped glass. The XLMA ytterbium doped fibers provide end users with high absorption and large core areas for multi-kW, multimode lasers and high pulse energy amplifiers. These fibers are also extremely well suited for making amplified spontaneous emission (ASE) sources with low spatial and temporal coherence which makes them ideal sources for full-field imaging and ranging applications. The fibers are offered with a triple clad geometry enabling multi-kW average powers and multi-MW peak powers.

This new class of XLMA fibers is expected to expand the frontiers of fiber lasers, amplifiers and ASE sources in materials processing, imaging and ranging applications.
