ABSTRACT:
A laser ablation process for preparing superconducting oxide thin films such as YBa.sub.2 Cu.sub.3 O.sub.7-x comprises ablating a target surface with pulsed laser beam to cause deposition of target molecules on a substrate. The incident laser beam on the target surface has an energy of 5 to 10 J/cm.sup.2 per pulse.
