heal.abstract	Two different kinds of chalcogenide glass IR fibers were evaluated relative to transmission of pulsed IR radiation produced by several laser sources in the wavelength range from I to 10 put. Fibers composed either from As-Se Te or from AS(2)S(3) glass, of 250, 500, 750 and 1000 mu n and 250, 750 and 1000 mu rn core diameters were studied, respectively. Attenuation measurements were obtained as a function of the laser energy input and as a function of curvature, wherever this was possible. The output beam quality was also studied using a beam profiler. The lasers used were a Q-switched Nd:YAG laser, emitting at 1.06 mu m, a free-running or Q-switched Er:YAG laser emitting at 2.94 mu m and a tunable pulsed CO2 laser emitting in the range of 9.3-10.6 mu m. The fibers exhibited better behavior when tested with the Er:YAG laser and they were found fragile in pulsed radiation from the Nd:YAG and the CO2 laser. The output beam profiles generally showed a central multi-spiking energy distribution. (C) 2007 Elsevier B.V. All rights reserved.	en
