Ytterbium fiber laser
Fibercore

Cladding-Pump' is perhaps the most significant innovation yet in the field of active fiber devices. By harnessing the high power outputs of multimode pump diodes, cladding-pump fibers have made the goal of multi-watt lasers and amplifiers a reality.

CP1100 employs Fibercore Limited's QPS (quasi polygonal, sinusoidal) fabrication technology (patents pending). The multi-lobed, pure-silica pump-core of CP1100 ensures that pump energy is transferred efficiently into the central, ytterbium-doped laser core whilst the circular cross section enhances compatibility with conventional optical fibers and components.

Unlike competitors' cladding-pump technologies, which employ a silicone rubber or low refractive index resin, CP1100 has a doped silica outer cladding. This unique construction dramatically improves and simplifies the handling characteristics of cladding-pump fibers - and can only increase both reliability and power-handling capabilities.
