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.

Beam Benders are the basic building blocks of a conventional beam delivery system. A mirror located inside a holder is employed to turn the beam at a 90° angle (other angles are also possible). Depending on the particular mirror, beam benders are compatible with CO2, Nd:YAG and Fiber lasers.
The mirror holder can also feature water-cooling provisions for use with higher power lasers. Laser Mechanisms provides two basic styles of Beam Benders - a knuckle style for use with the small aperture series and articulated arms, and a block style for the large aperture series. Beam Benders also provide adjustment capability to properly align and steer the laser beam. Interlocked versions are available as a safety feature for when the mirror cap is removed.

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.

Beamsplitters are used to split or combine beam of light. Plates and cubes are the most common types. The performance of beamsplitters are mainly depended on the coating specifications. In selecting beamsplitters, the forms, coating, transmission and damage threshold should be considered.

Beamsplitters are used to split or combine beams of light. Tower provides some standard beamsplitters, but most are custom made.
Plates are used for most laser applications as they exhibit low absorption. Cubes are a convenient, protected form for low power applications. The performance of the beamsplitters is a function of the beamsplitter coating.
Beamsplitter Cubes
These beamsplitters are based upon using two complementary prisms. The output beam, which is parallel to the input beam, is called the p-polarized beam, while the orthogonal output beam is defined as s-polarized.
Basic Specifications:
Material: BK7
Dimension Range: 3.2mm to 50.8mm
Surface quality: 60/40 scratch and dig
Principal transmittance: Tp > 95% and Ts < 1%
Principal reflectance: Rs > 99% and Rp < 5%
Wavelength range: 226nm to 2300nm
Beamsplitter Plates
Are primarily used to split or re-combine a beam of light, especially in high power lasers. When using beam splitter plates the two partial beams travel different optical paths. The optical paths depend on the incident angle and the thickness of the plates.

Thin Film Plate Polarizers and Dichroic Beamsplitters
Thin-film plate polarizers utilize our advanced ion-beam-sputtered (IBS) coating technology to achieve high-power performance and guaranteed transmission at a specific angle of incidence, with no angle tuning required. By combining durable dielectric coatings with fused silica substrates, we produce robust optical components that are stable, easy to align and exhibit high laser damage thresholds in both reflection and transmission.
High energy plate polarizers separate s and p polarizations with an extinction ratio (Tp/Ts) of greater than 750 to 1000:1 in the transmitted beam. Thus, they are ideal for intracavity or extracavity high-power applications where fluences are greater than 500 mJ/cm2 and calcite or cemented cube polarizers cannot be used.
Among the many diverse custom optical components that PPC offers are diode-pumped Nd:YAG resonator mirrors, 50/50 non-polarizing beamsplitters and thin-film plate polarizing beamsplitters. For all the optical components we provide, we use only ion-beam-sputtered (IBS) coatings. The IBS coating process is both accurate and repeatable, resulting in precision coatings that are easy to clean, chemically resistant and insensitive to moisture and other environmental factors.
