Fiberguide Industries has introduced its multimode, step-index optical fibres for high power laser beam delivery. The fibres feature an air-gap design, wherein the fibre extends into free space; this provides an epoxy-free region in which thermal energy can be safely dissipated without burning the surrounding material - a common cause of failure in standard connectors. To maximise power handling and beam uniformity, fibre end surfaces are cleaved and then laser polished to eliminate contaminants, scratches, chips and pits.
Standard core diameters of 100µm, 200µm, 300µm, 400µm, 600µm, 1,000µm and 1,500µm are available, with non-standard diameters available upon request.
