Fiberguide Industries Inc. has released a line of laser-delivery assemblies with a high-power SMA (HP-SMA) connector that uses air gap technology to eliminate energy-absorbing materials at the cantilevered fiber end. A heat sink is thermally and mechanically connected to conduct the generated heat away from the fiber. The HP-SMA design is offered in standard core diameters from 200 to 1500 µm, with numerical apertures of 0.12, 0.22, 0.26 and 0.39. Smaller-diameter fibers incorporate a fused-silica sleeve at the tip for support without adding energy-absorbing materials. A high-conductivity copper ferrule at the nose of the connector allows greater heat dissipation at higher power levels.
