heal.abstract	The radiation transmission of a Q-switched and a free-running Er:YAG laser, emitting at 2.94 mum, through high power (HP) oxide glass fibers of 450 mum and 250 mum core diameter was studied. Attenuation measurements were obtained as a function of the laser energy input and as a function of the curvature. The output beam quality was also studied using a beam profiler. Experiments with the same Er:YAG laser but with a 1000 mum core diameter cyclic olefin polymer coated silver hollow glass (COP/Ag) waveguide as the delivery system were performed for comparison. The results are promising as far as the delivery of Q-switched Er:YAG laser radiation is concerned. The fibers exhibited an attenuation below 0.7 dB/m, good output beam profiles, while no damage was observed after extended use. (C) 2003 Elsevier Science B.V. All rights reserved.	en
