SC400 is a high power fiber laser generating supercontinuum radiation in the 400 - 2500 nm spectral band with average power up to 6W. The laser consists of a master source based on the FemtoMaster1060, a custom made nonlinear high power fibre amplifier. The lasers are air-cooled, maintenance free and do not require any adjustments.

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. |

| Distributed Feedback (DFB) Diode Lasers are fixed wavelength single mode diode lasers. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material. The optical gain is provided by double heterostructure which include several Quantum Wells for electronic confinement. Typcal emitter width range between 3µm and 7µm. The single mode emission is enforced by a Bragg grating with the laser chip. The surfaces of the laser chip act as cavity mirrors due to the difference of the refractive index of the laser material and the surrounding air. The rear facet of the laser chip is provided with a high reflection coating. The front facet of the laser chip is provided with a high quality antireflection coating for avoiding the Fabry Perot modes of the laser chip. Distributed Feedback (DFB) Diode Lasers are available at almost any wavelength between 760nm and 2800nm. |

BC4 series diode laser beam combiners can combine up to four laser diodes with similar (at least two different wavelengths with 50 nm spacing) or disimilar wavelengths (at least 50 nm spacing) .
Photo monitor of the combined power output is an optional addition.
The standard package features an SMA receptacle for multimode fiber coupling. The combiners can accept both 5.6 mm and 9.0 mm TO packages. |

| Multimode, step-index optical fibers offer the most efficient and flexible delivery of high power laser beams. The correct components should be selected for minimizing beam quality degradation and optimum robustness. Smaller fibers tend to produce less degradation to beam quality but the minimum usable fiber size is limited by the quality of the laser beam, focusing optic and the numerical aperture (N.A.) of the fiber. Selection of the appropriate fiber type is an important consideration because the characteristics of the output beam will enhance or degrade the utility of the fiber optic delivered beam for different applications. The other components of the beam delivery system also impact performance: High power handling requires high quality end face surface finish and specially designed connectors that can withstand heating which comes from the absorption of spurious reflections or refractions at the fiber end faces. The fiber optic delivery system allows the laser beam to be transmitted in a small, flexible cable and is ideal when the laser beam must be delivered along a complex path or processing requires complicated manipulation of the beam delivery optics. |

OFS offers a suite of optical fibers, cables, and custom connectorized probes for delivering high laser powers for medical and industrial uses. We offer reusable fibers for aesthetic laser treatments and disposable fibers for urology. Industry uses our fibers in their lasers for cutting, welding, and etching.
Our HCXtreme™ Optical Fiber product line for high power under tight bends offers fibers in a selection of core sizes and numerical apertures, addressing the need to transmit high laser powers at the same time the fiber is subject to extreme bending conditions. Additionally, because many of these fibers are intended for intra-body use, they are biocompatible, non-toxic, and sterilizable.
Other large core HCS® optical fibers are available for specific applications. OH content, numerical aperture, core size, cladding and buffering materials can all be adjusted to meet specific needs. |
