Lumentum Advanced Specialty Optical Fiber Family

Lumentum’s Ytterbium-doped triple-clad fibers are specifically engineered for high-power laser and amplifier systems, offering outstanding performance and reliability at output powers up to 15 kW and beyond. Utilizing our proprietary vapor-phase technology, we tightly control dopant levels within the core glass matrix, minimizing photodarkening and maximizing efficiency. The triple-clad construction integrates an all-silica inner cladding with a robust, high-power-compatible outer coating, ensuring efficient pump guidance and effective thermal management under demanding conditions. Each fiber undergoes comprehensive screening for coating and glass imperfections, resulting in superior long-term reliability.

For specialized requirements, Lumentum offers custom fiber designs tailored to specific absorption levels, core numerical apertures (NAs), and geometric properties, enabling seamless integration across a wide range of industrial, scientific, and research applications.
