Abstract

Transmission efficiencies, damage thresholds and bend radii have been determined for six fluorozirconate fibres. Using pulsed radiation at 2.94μm, average powers up to 3.5W have been delivered with an efficiency of 65%. After taking into account reflection losses, maximum efficiencies near to 100% have been measured at low powers. Minimum damage thresholds of 3.7MW/cm2 have been observed and bend radii are approximately 25mm for a 300μm core.
