Velocity filtration of laser-induced plasma from droplets and solid particl
es has been successfully realized for infrared exciting radiation, Special
approaches to preparation of targets and substrates as well as laser beam p
rofiling have been proposed. Those new conditions enable reproducible on-ax
is deposition of particle-free YBa2Cu3O7-delta films with high-ir, by pulse
d YAG:Nd3+ lasers. (C) 2000 Elsevier Science B.V. All rights reserved.
