Paper Abstract

A pulsed Er:YAG laser and a preionized pulsed HF laser were used for the evaluation of the transmission properties of sapphire fibers and fluoride glass fibers. Both lasers provided an output of 100 mJ/pulse, with a repetition rate of 1Hz at 3 micrometers wavelength. The pulse duration of the two lasers was 200 ns for the HF and 80 microsecond(s) for the Er:YAG. The sapphire fibers were 0.25 m long with diameters varying from 585 to 850 micrometers . The fluoride fibers were flexible, 1.6m long, with inner diameters varying from 350 to 600 micrometers . The evaluation of the fiber properties include both straight and bend loss characteristics, the influence of the input power to the output power and the permitted misalignment of the fiber in respect to the optical axis.
