Mode Stripping SMA Cables for High Power Laser Systems

Fiberguide’s new line delivers up to 350W for material processing applications

Stirling, N.J. (September 29, 2011) –  Fiberguide’s new line of high power mode stripping SMA cable assemblies provides a higher power alternative to traditional laser delivery cables for high power laser welding, marking, cutting and drilling equipment. The assemblies have also proven effective for use as diode laser pigtails in diode pumped solid state (DPSS) systems.

Most similar products are unable to operate above 150W (200µm core) without active water cooling. Fiberguide’s new line is designed to handle more power and survive at higher temperatures with a passive, air-cooled design. An integrated mode stripper dissipates up to 25W of power from the cladding, ensuring a clean output and boosting power handling capacities to 100W (100µm core), 250W (200µm core) or 350W (400µm core), depending on system conditions.

Assemblies have an epoxy free cantilevered nose design, which isolates the optical fiber from the ferrule to prevent thermal and contamination problems. Fiber tips are laser polished for maximum transmission. Cables contain all silica fiber and are available with 100µm, 200µm and 400µm cores for easy integration into existing systems.

Single fiber assemblies with furcation and monocoil sheathing from Fiberguide Industries.

Single fiber assemblies with furcation and monocoil sheathing from Fiberguide Industries.

Single fiber assemblies are available with two choices of chemical resistant, non-magnetic sheathing to fit customers’ needs.  For general purpose use, Fiberguide’s furcation tubing is comprised of a Kevlar reinforced PVC sleeve over a polypropylene tube.  Furcation tubing is non-conductive and protects fibers with a liquid-tight seal.

For more specialized applications, Fiberguide offers stainless steel monocoil sheathing.  The monocoil is vacuum compatible and resistant to tight bending, crushing, cutting, kinking and high temperatures.

Both standard cable designs are rated for use at ambient temperatures.  Single fiber assemblies are available with core sizes ranging from 50µ to 1000µ and wavelengths from deep UV (DUV) to UV-VIS and VIS-IR.  Assemblies are also available upon request with ST and FC connectors, numerical apertures of 0.12 and 0.26, and continuous lengths up to 50 meters.

Fiberguide’s Plastic Clad Silica Fibers Offer Excellent UV and Infrared Transmission

Low and standard OH fibers feature plastic cladding to prevent fiber breakage

Stirling, N.J. (April 19, 2010) – For medical, scientific and military applications, Fiberguide Industries offers a full line of low and standard hydroxyl concentration (OH) plastic coated silica fibers.  The Anhydroguide™ and Superguide™ are low cost optical fibers that provide superior UV and infrared transmissions.

Fiberguide’s Anhydroguide fiber is constructed of a pure fused silica core, made by reacting silicon tetrachloride with oxygen using a plasma arc.  This ensures a low residual OH for excellent infrared transmission.  Superguide’s silica core is constructed in the same manner, only with an oxy-hydrogen flame instead of a plasma arc, which maximizes the fiber’s UV transmission properties.

Both fibers feature plastic cladding to protect the fiber during buffer stripping and prevent breakage, while increasing fiber strength and reducing static fatigue in humid environments.  Fibers offer exceptional transmission in tight bends, with a high core-to-clad ratio and numerical aperture of 0.37.  All materials used in construction are certified by NAMSA to USP Class VI for non-toxicity and biocompatibility.

Fiberguide’s Multimode Fibers Provide Accurate High Power Laser Delivery

Lightweight and flexible optical fibers eliminate heavy articulated arms

Stirling, N.J. (January 11, 2010) – Delivery of high power laser light in scientific, military, and industrial/ commercial applications normally requires bulky, inconvenient and often heavy articulated arms.  For a more efficient approach to laser delivery, Fiberguide Industries offers its multimode, step-index optical fibers.

Fiberguide’s multimode fibers are a simple way to accurately deliver high power laser beams.  They feature an air-gap design, where the fiber extends into free space.  This provides an epoxy-free region where thermal energy can be safely dissipated without burning the surrounding material, a common cause of failure in standard connectors.  To maximize power handling and beam uniformity, fiber end surfaces are cleaved and then laser polished to eliminate contaminants, scratches, chips and pits.

Standard core diameters of 100µ, 200µ, 300µ, 400µ, 600µ, 1000µ and 1500µ are available, with non standard diameters available upon request.  To aid in the correct fiber diameter selection for each particular application, Fiberguide’s new data sheets provide updated technical information.  To download a data sheet, visit the following link: http://fiberguideindustries.thomasnet.com/Asset/HighPower%2012-02-09.pdf.

Fiberguide’s Polyimide Optical Fibers for High Temperature Performance

Coating protects fibers in extreme thermal conditions

Stirling, N.J. (December 3, 2009) – Providing optimal performance of fiber optics in extreme conditions, Fiberguide Industries offers a full line of standard optical fibers with polyimide coating. 

Fiberguide's polyimide coated fibers for high temperature performance.

Fiberguide's polyimide coated fibers for high temperature performance.

Fiberguide’s polyimide coating is ideal for oil and gas, aerospace, sensors, defense, medical and security applications requiring high temperature resistance.  The coating withstands operating temperatures up to 400ºC (300ºC continuous), while conventional coatings such as acrylate, nylon and Tefzel® begin to deteriorate between 100ºC and 250ºC.  

Additionally, Fiberguide’s unique process of applying the coating results in a fiber of significantly reduced cross-sectional area.  This low profile characteristic is optimal for use in bundles and supports spectral transmission from 160nm to 2500nm.

Polyimide coated fiber is available in step index, multimode fibers from 50um cores to 600um cores; 6.25um/125um and 50um//125um graded index; and 4.8um/125um and 9.2um/125um single mode fibers.  The fiber offers high performance optical and mechanical specifications with tight dimension tolerances providing high uniformity and lot-to-lot consistency.
