‘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.



CP1100 can be mounted with standard ferrules, cleaved and fusion-spliced – just like any other optical fiber

2. The Mode Field Diameter is a nominal, calculated value, estimated at the operating wavelength(s) using typical value of numerical aperture and cut-off wavelength.
5. Background loss is quoted at a minimum point of the spectrum (typically 1100 nm to 1200 nm for the DF1500 series.
NB: The speed of development of cladding-pump technology is such that the specifications of CP1100 are subject to continuous review. Please contact Fibercore Limited for exact details of current specifications, as well as the availability of both alternative dopants and compatible passive components.
