Laser polished fiber face maximizes power transmission

Stirling, N.J. (August 21, 2012) – Fiberguide Industries’ new FD-80 high power keyed connector delivers unprecedented power handling up to 750 watts. The new assembly is designed for the demanding power requirements of industrial laser systems used for cutting, drilling, marking and welding.

Fiberguide’s FD-80 high power keyed connectors for industrial laser applications.

FD-80 connector assemblies are constructed from all silica optical fibers with core sizes from 100µm to 1500µm. An epoxy-free cantilevered nose design isolates fibers from the connector, allowing safe dissipation of thermal energy without burning the surrounding material. Connectors have a laser polished fiber face to promote better power transmission and reduce risk of damage to the end face.

Fiberguide’s connectors are available with anti-reflective coating and various sheathing options to best fit environmental conditions. Optional integrated mode stripping removes stray cladding power for systems requiring enhanced performance.

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.
